主　　题：Vehicle performance 

摘      要：This paper considers a full-vehicle model with preview control travelling on a random road. The road roughness is modelled as the PSD of the random road irregularity provided by integrated white noise which is estimated by a deterministic step input. The response of the vehicle model is optimised to improve the vehicle performance given by a performance index which is the weighted integral of suspension working space, tyre deflection and control force. The RMS values of control force, suspension space and tyre deflection are computed using the method of spectral decomposition. The results show that there is a substantial improvement in the vehicle performance in the case of linear-quadratic regulator with preview control compared to the linear-quadratic regulator without preview control.
