Abstract
Corrective control is able to compensate the stable state be- havior of a faulty asynchronous sequential machine in a de- sirable manner. In this paper, we present a scheme of fault diagnosis and tolerance for asynchronous sequential ma- chines with intermittent faults. The intermittent faults have the feature that their adverse effect continues for finite time during which the recovery to the normal status is impos- sible. Based on an event-based framework, we propose a corrective controller for which the closed-loop system can be immune against the attack of intermittent faults. The ex- istence condition for the controller is that there must exist an output equivalent state with the same reachability as the faulty state. An illustrative example is provided for demon- strating the controller design.
