Dong J and Yang G-H (2013), "Robust static output feedback control synthesis for linear continuous systems with polytopic uncertainties", Automatica. Vol. 49(6), pp. 1821-1829.
Abstract: This paper studies the static output feedback (SOF) control problem of continuous-time linear systems with polytopic uncertainties. Novel LMI conditions with a line search over a scalar variable for designing robust SOF controllers are proposed, where the uncertain output matrix of the considered system is allowed to be not of full row rank. In particular, it is shown that the new method can give less or at least the same conservative results than those methods by inserting a matrix equality constraint between system output matrix and Lyapunov matrix. Furthermore, the result is extended to the case of H ∞ control. Numerical examples are given to illustrate the effectiveness of the proposed method.

Abstract: Abstract This paper addresses the H[infinity] and mixed H2/H[infinity] control synthesis problems of nonlinear discrete-time systems, which are represented by a new type of T-S fuzzy models. The fuzzy systems consist of local nonlinear models and are with fewer fuzzy rules than the conventional T-S fuzzy systems with local linear models. A fuzzy control scheme with local nonlinear feedbacks is proposed and H[infinity] and mixed H2/H[infinity] control synthesis conditions are given in terms of solutions to a set of linear matrix inequalities (LMIs). In contrast to the existing conditions for designing fuzzy controllers, the new ones can be used to design fuzzy controllers based on fewer control rules as well as are with less computational burden. In particular, the new methods can also give less conservative results. A numerical example is given to illustrate the effectiveness of the proposed methods.

Abstract: This paper considers the output feedback control problem for nonlinear discrete-time systems, which are represented by a type of fuzzy systems with local nonlinear models. By using the estimations of the states and nonlinear functions in local models, sufficient conditions for designing observer-based controllers are given for discrete-time nonlinear systems. First, a separation property, i.e., the controller and the observer can be independently designed, is proved for the class of fuzzy systems. Second, a two-step procedure with cone complementarity linearization algorithms is also developed for solving the H[infinity]; dynamic output feedback (DOF) control problem. Moreover, for the case where the nonlinear functions in local submodels are measurable, a convex condition for designing H[infinity]; controllers is given by a new DOF control scheme. In contrast to the existing methods, the new methods can design output feedback controllers with fewer fuzzy rules as well as less computational burden, which is helpful for controller designs and implementations. Lastly, numerical examples are given to illustrate the effectiveness of the proposed methods.

Abstract: This paper is concerned with the problem of designing fuzzy controllers for a class of nonlinear dynamic systems. The considered nonlinear systems are described by T-S fuzzy models with nonlinear local models, and the fuzzy models have fewer fuzzy rules than conventional T-S fuzzy models with local linear models. A new fuzzy control scheme with local nonlinear feedbacks is proposed, and the corresponding control synthesis conditions are given in terms of solutions to a set of linear matrix inequalities (LMIs). In contrast to the existing methods for fuzzy control synthesis, the new proposed control design method is based on fewer fuzzy rules and less computational burden. Moreover, the local nonlinear feedback laws in the new fuzzy controllers are also helpful in achieving good control effects. Numerical examples are given to illustrate the effectiveness of the proposed method.

Dong J and Yang GH (2011), "Control Synthesis of T-S Fuzzy Systems Based on a New Control Scheme", IEEE Transactions on Fuzzy Systems. Vol. 19(2), pp. 323-338.
Abstract: This paper studies the control synthesis problem of Takagi–Sugeno (T--S) fuzzy systems. By splitting the premise variable spaces and using the properties of fuzzy sets, a new control scheme is proposed based on a new class of fuzzy Lyapunov functions, and a convex condition for designing fuzzy controllers is given, where the new fuzzy Lyapunov functions and fuzzy controllers are constructed based on the split subspaces. In particular, some existing fuzzy Lyapunov functions and control schemes are special cases of the new Lyapunov function and control scheme, respectively. Numerical examples are given to illustrate the effectiveness of the proposed method.

Abstract: This paper is concerned with the problem of designing robust H[infinity] static output feedback (SOF) controllers for a class of discrete time nonlinear systems, which are represented by T-S fuzzy models. By considering the properties of system output matrices, a method for H[infinity] SOF control synthesis is developed in terms of solutions to a set of linear matrix inequalities (LMIs). In contrast to the existing techniques for designing SOF controllers, the new proposed method can give less conservative results by removing the constraint that the considered Lyapunov matrix is diagonal. Numerical examples are given to illustrate the effectiveness of the proposed design method.

Abstract: This paper studies the problem of dynamic output feedback H[infinity] control of discrete-time Takagi-Sugeno (T-S) fuzzy systems via a switched dynamic parallel distributed compensation (DPDC) scheme. The considered switched DPDC control structure is determined based on the values of membership functions. Some new properties of membership functions are obtained, and exploited to derive sufficient conditions for designing switching DPDC controllers that guarantee the stability and H[infinity] performances of closed-loop nonlinear systems. The design conditions are given in terms of solvability of a set of linear matrix inequalities (LMIs). It is shown that the new approach provides results at least as good as the corresponding DPDC methods. A numerical example is given to illustrate the effectiveness of the proposed approach.

Abstract: This paper addresses the H[infinity] control problem via slow state variables feedback for discrete-time fuzzy singularly perturbed systems. At first, a method of evaluating the upper bound of singular perturbation parameter [epsilon] with meeting a prescribed H[infinity] performance bound requirement is given. Subsequently, two methods for designing H[infinity] controllers via slow state variables feedback are presented in terms of solutions to a set of linear matrix inequalities (LMIs).

Finally, two numerical examples are given to illustrate the effectiveness of the proposed methods.

Abstract: This paper studies the problem of state feedback control of continuous-time T-S fuzzy systems. Switched fuzzy controllers are exploited in the control design, which are switched based on the values of membership functions, and the control scheme is an extension of the parallel distributed compensation (PDC) scheme. Sufficient conditions for designing switched state feedback controllers are obtained with meeting an H[infinity] norm bound requirement and quadratic stability constraints. It is shown that the new control design method provides less conservative results than the corresponding ones via the parallel distributed compensation (PDC) scheme. A numerical example is given to illustrate the effectiveness of the proposed method.

Abstract: This paper considers the problem of designing stabilizing and H-infinity controllers for nonlinear singularly perturbed systems described by Takagi-Sugeno fuzzy models with the consideration of the bound of singular perturbation parameter epsilon. For the synthesis problem of simultaneously designing the bound of epsilon and stabilizing or H-infinity controllers, linear matrix inequalities (LMI)-based methods are presented. For evaluating the upper bound of epsilon subject to stability or a prescribed H-infinity performance bound constraint for the resulting closed-loop system, sufficient conditions are developed, respectively. For the stabilizing and H-infinity control synthesis without the consideration of improving the bound of epsilon new design methods are also given in terms of solutions to a set of LMIs. Examples are given to illustrate the efficiency of the proposed methods.

Abstract: This paper considers the problem of designing $H_infty$ filters for fuzzy singularly perturbed systems with the consideration of improving the bound of singular-perturbation parameter $epsilon$. First, a linear-matrix-inequality (LMI)-based approach is presented for simultaneously designing the bound of the singularly perturbed parameter $epsilon$, and $H_infty$ filters for a fuzzy singularly perturbed system. When the bound of singularly perturbed parameter $epsilon$ is not under consideration, the result reduces to an LMI-based design method for $H_infty$ filtering of fuzzy singularly perturbed systems. Furthermore, a method is given for evaluating the upper bound of singularly perturbed parameter subject to the constraint that the considered system is to be with a prescribed $H_infty$ performance bound, and the upper bound can be obtained by solving a generalized eigenvalue problem. Finally, numerical examples are given to illustrate the effectiveness of the proposed methods.

Abstract: This paper considers the H∞ dynamic output feedback (DOF) control problem for nonlinear discrete-time systems, which are represented by a new type of T-S fuzzy systems with local nonlinear models. A class of DOF controllers with local nonlinear dynamic structures are proposed and a convex controller design method is developed. In contrast to the existing methods, the new method can design dynamic output feedback controllers with fewer fuzzy rules as well as less computational burden. A numerical example is given to illustrate the effectiveness of the proposed methods.

Abstract: This paper is concerned with the stability analysis for T-S fuzzy control systems. By exploiting the property of the structure of fuzzy inference engine, an equivalence relation on index set of the product of rule weights is defined. Further, a new class of stability analysis conditions is proposed by using the equivalence classes under the relation. In contrast to the existing results, the new conditions are with less conservatism and a lighter computational burden. Numerical examples are given to illustrate the effectiveness of the proposed methods.

Li Z, Dong J and Yang G-H (2013), "Diagonal dominance for flight control systems of canard aircraft in finite frequency range", In 25th Chinese Control and Decision Conference (CCDC). , pp. 1983-1988.
Abstract: This paper presents a new method for determining a constant precompensator for reducing the effects of interactions of the flight control systems in Canard Aircraft. However, the previous methods achieve diagonal dominance either at a certain suitable frequency or across the entire frequency domain. Taking the practical engineering situation into consideration, it is necessary to achieve diagonal dominance among a specific section instead of the whole of the frequency domain. This paper combines the LMIs and the Generalized KYP Lemma to obtain a new method to solve the problem. The algorithm is then modified to reduce the conservatism by the introduction of a path-shaping matrix. The path-shaping matrix enables a designer to find an optimal precompensator to achieve a specific forward path structure and a satisfactory output response. The algorithm is applied to a Canard Aircraft flight control system. Simulations show the new approach can more effectively decouple the Canard Aircraft system than other approaches.

Abstract: This paper is concerned with the design of static output feedback(SOF) fuzzy controllers for a continuous-time Takagi-Sugeno fuzzy system with sensor faults. By introducing a particular change of variable, a convex sufficient condition with a line search over a scalar variable for designing fault tolerant SOF controllers is given in terms of a family of linear matrix inequalities. In contrast to some existing approaches, the new condition removes the equality constraint between the output matrix and Lyapunov matrix, then can reduce the conservatism of the existing conditions. Finally, a numerical example is given to verify the effectiveness of the proposed method.

Abstract: This paper studies robust stability of linear systems with polytopic uncertainty. New necessary and sufficient conditions for the existence of an affine parameter-dependent Lyapunov function assuring the Hurwitz or Schur stability of a polytopic system, which are composed of a family of linear matrix inequality conditions of increasing precision. At each step, a set of linear matrix inequalities provides sufficient conditions for the existence of the affine parameter-dependent Lyapunov function, and necessity is asymptotically attained. Compared with the existing results in the literature, it is shown that the new stability conditions provide less conservative tests at each step. A numerical example is given to illustrate the effectiveness of the new results.

Abstract: The 3DOF helicopter system is a multi-variable and strong coupled system. This paper is concerned with input-output energy decoupling and presents a new input-output energy decoupling conditions for 3DOF helicopter system. The previous methods achieve input-output energy decoupling in entire frequency range and often with additional conditions, which is not completely adopted to practical situation. Therefore, it is necessary to achieve input-output energy decoupling in a finite frequency range and without additional conditions. The new input-output energy decoupling conditions are proposed in this paper as a finite-dimensional convex optimization problem described by linear matrix inequalities (LMIs) to solve this problem, which is with less conservatism. The algorithm is applied to 3DOF helicopter system and the simulation results are given to illustrate the effectiveness of the proposed new decoupling methods.
