Satisfactory fault tolerant control for uncertain discrete time delayed systems against actuator failures

The problem of state feedback satisfactory fault-tolerant control is investigated for uncertain discrete-time delayed systems against actuator failures.Sufficient conditions for the existence of robust fault tolerant stabilization controllers with time-dalay memory are given.Then,the satisfactory fault tolerant controllers with H∞ constraints are designed based on the solutions of a group of linear matrix inequalities.Numerical examples show the effectiveness of the results.
