H/sub /spl infin// active suspension control based on moving horizon strategy

A moving horizon H/sub /spl infin// disturbance attenuation scheme for active suspensions with time-domain constraints is suggested, where closed-loop dissipation and hence H/sub /spl infin// performance are guaranteed. By minimizing the performance level online, the closed-loop system is able to relax the performance requirement so as to meet hard constraints in the case of unforeseen large disturbances, and to recover a better performance in the case of generally mild disturbances. Simulation results for a 2 DOF quarter-car model are presented.
