Abstract

This paper presents a new scheme of generating residuals for use with reconfigurable control systems, where speed and resolution of failure detection are of paramount importance. The scheme employs parity checks which are performed on a set of filtered measurements. The main challenge lies in the need to simultaneously design a filter gain and a parity vector. A means of measuring the performance is established, based on which an iterative design procedure is developed. Performance comparison with the standard parity space approach is made with regard to disturbance rejection, failure sensitization, and processing requirement reduction
