This study focuses on passive fault-tolerant control for a class of uncertain nonlinear discrete-time systems subject to multiple intermittent faults. The considered intermittent faults are assumed to be additive ones in sensors and/or actuators. To achieve fault-tolerant control, a dynamic output-feedback controller is designed such that the closed-loop system remains stable and satisfies acceptable performance, even when there are parameter uncertainties, nonlinearities of specific type, and multiple additive intermittent sensor and/or actuator faults. The linear matrix inequality method is employed to obtain sufficient conditions for achieving fault tolerance and ensuring the prescribed H_∞$H_{\infty }$ performance index. Finally, the effectiveness of the proposed method is demonstrated by simulation examples.
