PROJECT TITLE :

Simultaneous control and fault detection for discrete-time switched delay systems under the improved persistent dwell time switching

ABSTRACT:

This study is devoted to simultaneous management and fault detection for discrete-time delay switched systems. In the persistent dwell time (PDT) switching framework, a a lot of general switching law is intended, where the resulting PDT depends on the state delay. For delay switched systems, the result shows the relation between PDT and state delay. More importantly, it also includes the previous delay-independent ends up in special case. Next, underneath the switching law, the time-varying output-feedback-based controller/residual generators are provided such that the closed-loop system is with the non-weighted H_ index for fault and l2-gain for disturbance. Compared with the present methodology below the common dwell time switching, the method proposed here leads to higher fault sensitivity. Finally, a simulation example is exploited to demonstrate the effectiveness of the proposed results.
