N2 - Windup is a problem in control of time delay systems which is produced due to saturated actuators that may lead to oscillations and long settling times as well as instability. This problem is addressed by designing an anti-windup compensator (AWC), which makes the system performance better in the case of actuator saturation. There are different techniques to design AWC for linear, nonlinear and time-delay systems. One of them is decoupled architecture based technique, which provides better performance. It is used for linear and nonlinear systems so for. In this paper, the work on decoupled architecture based AWC design technique is further enhanced for time-delay systems. A novel architecture to design AWC for linear time-delay systems containing state-delays is proposed. Further, linear matrix inequalities are formulated which ensures performance and stability in order to deal with windup problems. A numerical example, provided, validates the proposed framework for time-delay systems.
