|Abstract:||This study solves a new fault detection strategy for vehicle active suspension systems in finite-frequency domain. Three fault detection filters are constructed in different finite frequency domains, which ensure that the error between residuals and faults is minimum. The H∞ filter problem is used to figure out the design problem of fault detection. The conditions of residual systems meeting H∞ performance are obtained by considering generalised Kalman-Yakubovich-Popov lemma and stability theory. The problem of filter design is solved by an optimisation algorithm. Illustrative examples are given to show the proposed design method's effectiveness and potential.|
