Detection Signal Design for Failure Detection and Isolation For Linear Dynamic System

Abstract : We present a new methodology to calculate a filter that permits failure detection and isolation in a dynamic system. Assuming that the normal and the failed behaviors of a process can be modeled by two linear systems subject to inequality bounded perturbations, a method for on line implementati-on of a detection signal, guaranteeing detection of failure, is presented. To make the failure detectable, the injection of the test signal that improves the detectability property of failure in the dynamic process is proposed which achieves detectability on line. All the operations needed for our method are implemented by using large linear optimization problem. Examples are shown.
