Abstract
This chapter considers a joint design problem for a vehicle active suspension system to optimize system parameters and a controller with constraints simultaneously. A model of quarter-car system with an active suspension is presented first. In view of the practical constraints of the acting force and suspension stroke, a mixed H∞/GH2 control is employed to attenuate the vibration of the system. By considering that both the controller and parameters of the system have great effect on the control performance, this chapter uses genetic algorithm (GA) to search for the desirable parameters and obtain the corresponding controller jointly. Simulations are given to demonstrate the effectiveness and superiority of the joint design approach in comparison with the open-loop, non-optimized and partly optimized systems.
