Control of discrete-time systems with actuator nonlinearities: an LMI approach

This paper considers the problem of stabilization of discrete-time systems with actuator nonlinearities. The proposed framework is based on a linear matrix inequality (LMI) approach and directly accounts for robust stability and robust performance over the class of actuator nonlinearities. Furthermore, it is directly applicable to actuator saturation control and provides state feedback controllers with guaranteed domains of attraction
