Design of a simulator of one-wheel EV system for testing of slip-prevention controller

In this paper, a simulator of one-wheel EV system is designed for testing of slip prevention controller by using M-G set. The drive motor of the M-G set is used to simulate the drive wheel of the EV, and the load motor is used to simulate the load force of the chassis. In driving process, the torque of the load motor is changed according to the drive force of the chassis that is calculated by the program. So it can simulate the dynamic process of the tire-road system. Based on this simulator system, a novel slip controller with inertia regulator is proposed and tested. The simulation results simulated by MATLAB and the experiment results have the same features and the results verified the simulating performance of the M-G system. And the experiment results proved the validity of the slip controller.
