Abstract :
This paper is concerned with the problem of fault detection filter for vehicle active suspension systems. The aim of this paper is to design a fault detection filter in finite-frequency domain. A sufficient condition for residual system with the prescribed H∞ performance index is derived based on the generalized Kalman-Yakubovich-Popov (KYP) lemma. In view of the obtained condition, the fault detection filter is designed in middle-frequency domain. A numerical example shows the effectiveness and potential of the proposed results.
