Abstract :
A moving horizon H∞ disturbance attenuation scheme for active suspensions with time-domain constraints is suggested, where closed-loop dissipation and hence H∞ 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.
