Traction control of electric vehicle by model predictive PID controller

Abstract

This paper proposes a new model predictive PID control method for the traction control of EV (electric vehicle). The method aims to improve the vehicle dynamics performance and the stability of EV by controlling the tire slip rate. In the proposed method, the PID controller gains are derived by off-line calculation from the optimal control input based on the model predictive control (MPC) algorithm. Numerical simulation results demonstrate the effectiveness of the proposed method. © 2011 The Japan Society of Mechanical Engineers.
