【Abstract】 A model of the integrated dynamic control system of electric power steering(EPS) and active-suspension is set up according to the principle of vehicle system dynamics. Simulation calculations have been done in regard to the steering system with the PD controller, the suspension with the optimization controller and the integrated system with the integrated controller. The simulation results prove that the model proposed shows the car’s steering action in real condition and the integrated controller is better than the seperate controller. The presented work is helpful to the integrated structure/control design for the EPS and active-suspension system.更多还原
