Simultaneous fault detection and control for discrete-time switched systems under relaxed persistent dwell time switching
作者:
Highlights:
• The switching rule is constructed in the frame of persistent dwell time (PDT). A switching number constraint condition derived from the average dwell time (ADT) is added to the PDT condition. This allows a much smaller dwell time lower bound of PDT, which provides more degree of freedom of designing switching signals.
• Compared with the existing time invariant output feedback controllers/detectors, the proposed time varying ones matching different switching processes of PDT are constructed such that the resulting closed loop systems are with better performance.
• A class of non weighted fault detection and robust control performance indexes are guaranteed under the proposed novel switching rule, which characterized the levels of fault sensibility and robustness.
