CSA-T-TDS Toolbox(时滞系统完全稳定性分析工具箱)
CSA-T-TDS Toolbox
A MATLAB toolbox for complete stability problem w.r.t. delay of time-delay systems
The CSA-T-TDS toolbox is developed to study the complete stability problem w.r.t. the delay parameter for a time-delay system with commensurate delays. It is quite user-friendly and simple-to-implement, equipped with graphical user interface (GUI). The toolbox works in a semi-automatic manner. In most cases, the user does not need to manually revise the data when CSA-T-TDS performs the analysis.
PS : The “Complete stability problem w.r.t. delay” refers to the problem of studying stability property of a system along the whole delay axis. The solution of complete stability problem gives the entire delay set where the system is asymptotically stable. Please do not confuse the complete stability problem with the delay-independent stability problem. The latter is only to study whether a system is asymptotically stable for all non-negative delay values. The latter is “included” by the former.

PID-Design-Delay Toolbox
A Matlab Toolbox for PID Controller Design for Time-Delay Systems
The proportional-integral-derivative (PID) controller design for time-delay systems is a classical and common problem with theoretical and practical significance. We consider a general case that all controller gains (kP,kI and kD) and delay (τ) are treated as free parameters. Our objective is to characterize stability set in the (kP, kI, kD, τ)-space. The problem is rather involved due to the mathematical difficulties. We developed a MATLAB-based toolbox, called PID-Design-Delay toolbox, based on some recent theoretical results. The user only needs to input the necessary information through the graphical user interface (GUI) and then the toolbox may automatically fulfill the analysis.
