IMC-PID traction control system for an automobile via engine torque control

Abstract

Trends in the automotive control systems are toward more comprehensive and electronic control. The objective of this paper is to study the effectiveness of Internal Model Control PID (IMC-PID) method to develop a traction control system based on engine torque control for an automobile. A plant model is developed based on the governing equations and implemented in MATLAB. This is then captured in a Simulink model and simulated to evaluate performance of the open-loop system for both step and ramp inputs. A proportional-integral (PI)-type controller is then developed using IMC-PID tuning method to improve closed-loop system response. Finally, potential future applications and research opportunities are identified.
