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

摘要

The robust stabilization problem for a class of uncertain lineartime-delay systems containing sector actuator is considered in thispaper. The unchain time-delay systems under consideration aredescribed by state differential equations with time-varyingunknown-but-bounded uncertain parameters and delayed state. The delayis assumed to be constant bounded but unknown. The new criterion ofdelay-dependent robust stabilizability for uncertain time-delaysystems is presented and he corresponding robust memoryless statefeedback controller is derived in terms of the solutions of severallinear matrix inequalities (LMIs). Numerical example is presented toillustrate the obtained results.
