Abstract


The problem of optimal vibration control for vehicle active suspension systems under road rough-ness disturbance is considered. First, the models for two-degree-freedom quarter-car suspension systemunder road roughness disturbance are presented, and road disturbances are considered as the output of anexosystem. Then, the feedforward and feedback optimal vibration control (FFOVC) law for vehicle active sus-pension systems is obtained and the existence and uniqueness of the FFOVC is proved. A state observeris designed to solve the problem of the physically realizable for the feedforward compensator. Numericalsimulations illustrate the effectiveness of the FFOVC law.
