102 新型アクティブサスペンションの構造と制御系の最適化に関する研究

抄録

In this paper, we deal with solving optimal design problems of a new type active suspension and its control system based on a modified genetic algorithm. The problems aim to pursue the improvement of vibration isolation performance to the limit. We consider simultaneously to optimize a state feedback gain vector of the control system and structural parameters of the suspension, i.e., stiffness of a spring and damping coefficient of a dash pod. As for active suspension of a 1/4 passenger car model, we do to optimize a feedback control gain vector and structural parameters simultaneously. Then, we show to be able to design an active suspension by which a vehicle body hardly receives the influence of road disturbance.
