Abstract :
Based on H∞ theory and state-observer theory in time-delay systems, a method of designing controllers for time-delay systems with sensor failures is presented. The controller designed by the proposed method can guarantee the stability of the resultant closed-loop systems and keep certain H∞ norm performance in the normal condition as well as in the event of sensor failures. A numerical example shows the validity of the proposed approach.
