Abstract

The active fault-tolerant control (FTC) problem for discrete-time systems in finite-frequency domain is addressed based on faults’ estimation. By the descriptor system approach, the observers are designed such that the stability and H_∞ performance index of dynamic error systems are analyzed in finite frequency domain. The estimation of faults is obtained by the designed observers. By using the estimation of faults, a H_∞ FTC method is presented to show the stability analyses of closed-loop systems in term of GYP lemma. Numerical simulations are given to demonstrate proposed FTC methods’ effectiveness.
