Abstract

For the velocity tracking control of electric vehicle, the classical control algorithm is difficult to obtain high precision. Modern control algorithms can improve the control accuracy but they require accurate vehicle dynamics modeling. For this situation, a hierarchical model predictive control(MPC) strategy is proposed. Compared with traditional vehicles, electric vehicles are driven by motors, which are more suitable for model predictive control.In the proposed strategy, the controller can adaptively adjust the acceleration to track the expected velocity without accurate vehicle model.An upper MPC controller is designed to uses the expected velocity and the actual velocity to calculate the expected acceleration. The lower controller establishes the vehicle inverse dynamics model to calculate the expected opening degree of the accelerator pedal and the braking pressure through the Inverse dynamics model of vehicle. Simulation results demonstrate that the the controller has a fast response and accurate tracking performance without overshoot.
