Abstract

Robust fault-tolerant H_∞ control against actuator failures and/or sensor failures is investigated for a class of uncertain descriptor systems via dynamical compensators. Based on H_∞ theory, sufficient conditions for the existence of dynamical compensators are derived. The dynamical compensators guarantee that the closed-loop descriptor systems are admissible and maintain certain H_∞ norm performance in the event of actuator failures and/or sensor failures as well as in the normal case. A simulation result shows the effectiveness of the proposed method.
