Study on Improving Riding Comfort of Tipper

For improving Riding Comfort, an adaptive fuzzy PID control method is proposed for the semi-active suspension model of engineering vehicle with five degrees of freedom based on the advantages of fuzzy control and adaptive PID control. Taking a tipper as the study object, an adaptive fuzzy PID controller is designed for vibration control of the engineering vehicle and is simulated. The performance indexes of the semi-active suspension system applied to adaptive fuzzy PID control strategy have different degree improvements, such as the pitch acceleration of sprung mass, vertical acceleration of passenger. So semi-active suspension of engineering vehicle adopting adaptive fuzzy PID control is feasible and can improve well in riding comfort for engineering vehicle.
