This paper deals with asymptotic tracking for linear systems with actuator saturation in the presence of disturbances. Both reference inputs and disturbances are assumed to belong to a class which may be regarded as the zero-input responses of linear systems. The controller includes an anti-windup term which reduces the degradation in the system performance due to saturation. The stability of the overall system is established based on the Lyapunov stability theory. Both state and output feedback solutions are given. The proposed scheme is evaluated for a two axis motion control system by simulation. [S0022-0434(00)01002-9]
