Output feedback stabilization of uncertain time-delay systems containing saturating actuators

Abstract

The robust output feedback stabilization problem for a class of uncertain linear time-delay systems containing a saturating actuator is studied in this paper. The systems are described by state differential equations with bounded time-varying uncertain parameters and unknown constant delay in the state. New criterion for robust stabilizability of the uncertain time-delay systems is presented and the corresponding observer-based robust output feedback controller is derived in terms of the solutions of linear matrix inequalities (LMIs). Simulation results show that the obtained method is feasible.
