Sliding Mode Methods in Electric Vehicle Stability Control

Abstract

This work is dedicated to brake-based stability control system for electric vehicles. The aim of the research is to compare four control methods: first-order sliding mode (FOSM), second-order sliding mode (SOSM), integral sliding mode (ISM), and variable-structure PI (VSPI). For this purpose, an evaluation methodology based on the weighted control performance index (WCPI) was developed. The comparative analysis is conducted with an experimentally validated vehicle model in IPG CarMaker® and MATLAB/Simulink co-simulation environment including high-fidelity vehicle subsystems' models.
