Computer Aided Control System Design for Time Delay Systems Using MATLAB

Computer Aided Control System Design (CACSD) allows to analyze complex interconnected systems and design controllers achieving challenging control requirements. We extend CACSD to systems with time delays and illustrate the functionality of Control System Toolbox in MATLAB for such systems. We easily define systems in time and frequency domain system representations and build the overall complex system by interconnecting subsystems. We analyze the overall system in time and frequency domains and design PID controllers satisfying design requirements. Various visualization tools are used for analysis and design verification. Our goal is to introduce these functionalities to researchers and engineers and to discuss the open directions in computer algorithms for control system design.
