Design of Longitudinal Control System for Brushless Motor Electric Vehicle Using VSTC Control Theory

Abstract

This paper is concerned with the design of a slide mode control system from the view point of practical application. The problem is treated using the asymptotic reaching law method for assuring global stabilization, and the chattering phenomenon is alleviated by the saturated function of the boundary layer. The design algorithm is simple and applicable to a nonlinear system including disturbances and uncertainties with high robustness. Its effectiveness is proven by simulation as well as a bench experiment of a brushless motor vehicle.
