Abstract :
The problem of robust Hinf reliable control with exponential stabilization is investigated for time-varying delayed uncertain systems against actuator failure. Based on Lyapunov stability theory, a sufficient condition of the existing of robust reliable controller with exponential stability is given. At the same time, another sufficient condition of the existing of robust reliable controller possessing Hinf performance index is presented. Those conditions are transformed to two linear matrix inequalities (LMIs). The resulting control systems retain robust reliable exponential stability and disturbance attenuation with Hinf-norm bounds despite any outages of actuator.
