This brief addresses the problem of control for active vehicle suspension systems in finite frequency domain. The performance is used to measure ride comfort so that more general road disturbances can be considered. By using the generalized Kalman-Yakubovich-Popov (KYP) lemma, the norm from the disturbance to the controlled output is decreased in specific frequency band to improve the ride comfort...
This paper addresses fault detection issues of railway vehicle suspension systems using a robust fault detection observer designed based on generalized Kalman-Yakubovich-Popov(GKYP) lemma. Two kinds of faults, a secondary lateral damper failure and a lateral accelerometer failure, are concerned. The simulation result shows that the robust fault detection observer is effective for the underlying fault...
The paper deals with the reliable Hinfin filtering problem for linear uncertain continuous-time systems with bounded disturbances. Different from the existing approaches, the filter is designed in certain finite frequency ranges, which is important in practice, since the full frequency approaches are conservative to some extent for the case when the frequency ranges of disturbances are known beforehand...
