Research on Sliding Mode Control of Micro-Low-Speed Electric Car for Lateral Motion

This paper studies how to improve the stability of micro-low-speed electric car (MEC) by direct yaw moment control. Taking the MEC as the research object, a two-degree-of-freedom vehicle model is established. The desired yaw rate based on the zero-sideslip-angle is taken as the desired value, a MEC lateral stability control strategy based on sliding mode control (SMC) is proposed. The simulation results on MATLAB/Simulink platform show that the designed control strategy can improve the Lateral stability of MEC. However, there is still room for improvement in solving the chattering problem in the control process.
