Stability and dynamic control of four in-wheel motored vehicle using fuzzy PID controller

Abstract

The yaw rate and the body sideslip angle (BSA) of vehicle are the most important parameters to describe vehicle stability and performance. The main goal of this paper is to improve the stability of in-wheel motored vehicle, this will be done by construct Simulink model using Matlab includes 2DOF vehicle dynamics as a reference model, 4 four wheel drive nonlinear vehicle model, and the structure of the fuzzy PID controller. Compared to conventional PID controller, the fuzzy PID controller can regulate the proportional, integral, and derivative parameters and improve the responds of vehicle system. Many simulation results show the vehicle stability control system using fuzzy PID controller can improve the handling and stability of the vehicle. © June 2016 IJENS.
