robust fault detect ion discrete time-delay systems filter H∞cont rol
A robust fault detect ion scheme is proposed for a class of discrete t ime-delay systems w ith uncertainty. The fault detect ion f ilter is designed by using H ∞cont rol theory. The robustness of the residual to uncertainty is proved and the gain mat rix of the f ilter is also val ued. Simulation results illust rated the validity of the proposed scheme.
