Abstract :
This paper is devoted to stability analysis and anti-windup design for linear time-delay systems subject to actuator saturation. A new Lyapunov-Krasovskii approach is presented, and a direct design algorithm is derived to compute the anti-windup compensator gain, which reduces the conservatism greatly. Both delay-independent asymptotic stability (DIAS) and delay-dependent asymptotic stability (DDAS) are dealt with respectively. Numerical examples are employed to demonstrate the effectiveness of our approach.
