ROBUST STABILIZATION OF UNCERTAIN TIME-DELAY SYSTEMS CONTAINING NONLINEAR SATURATING ACTUATORS

Abstract: The robust stabilization problem for a class of uncertain linear time-delay systems containing sector saturating actuator is considered in this paper. The uncertain time-delay systems under consideration are described by state differential equations with time-varying unknown-but-bounded uncertain parameters and delayed state. The delay is assumed to be constant bounded but unknown. The new criterion of delay-dependent robust stabilizability for uncertain time-delay systems is presented and the corresponding robust memoryless state feedback controller is derived in terms of the solutions of several linear matrix inequalities (LMIs). Numerical example is presented to illustrate the obtained results.

Key words: linear time-delay systems, state feedback, uncertainty, saturating actuator, delay-dependent, linear matrix inequality (LMI)
