✦ Synopsis

The paper deals with the global stabilization of linear systems with saturating actuators. A saturated state feedback control law containing an integrating action and a specific anti-windup compensator with nonlinearities of the dead-zone type are simultaneously synthesized to guarantee the global asymptotic stability of the closed-loop system. The approach is direct in the sense that both the proposed control laws are computed simply from a Lyapunov equation based on the controlled system. The controls are allowed to saturate and the steady-state error due to admissible constant perturbations can be brought to zero.

An anti-windup-based approach is newly attempted to deal with time-delay control systems with input saturation. Following the anti-windup paradigm, we assume that controllers have been designed beforehand for time-delay control systems based on existing design techniques which will show desirable pe

For a wide class of linear saturated systems, we address the anti-windup synthesis problem. By absorbing the actuator dynamics into the augmented system, we show that the original system can be simplified to a larger system with only amplitude saturation. The static anti-windup gain is therefore obt
