Optimal output feedback stabilization of active suspension control using acceleration measurement

This paper presents an application of the optimal fixed-order compensation technique for an active suspension system which provides superior ride comfort and racing vehicle performance. The controller uses acceleration measurement. The dimension of the compensator can be determined a priori for a fixed-order control methodology. The convergent algorithms are provided to find the optimal gain matrix subject to the performance index. The performance can be chosen to emphasize the ride comfort, road holding, working space of the suspension and power requirements. Computer simulations show that the proposed active suspension possesses much better performance than passive designs.
