The performance evaluation considers the displacement and acceleration of vehicle pitch-heave, left-right roll and up-down rise-fall, which are the key factors for a ride. By heuristic turning of the optimal weighting parameters achieves a sup-optimal optimization. The simulation result shows that both control and LQG control improve the heave-roll-pitch reponse effectively, moreover controller performs better than LQG controller.
