Design of Adaptive Sliding Mode Controller for Vehicle Suspension System

Abstract

In today’s world active suspension system is a hot issue in the recent research of automotive industry, which is to generate active force to suppress the variation of the vehicle and improve safety and comfort for the passengers. The tracking control problem of vehicle suspension system designed and simulated using sliding mode control with integrator. For comparative purpose controller is designed for the suspension system using fuzzy logic control. The influence of parameter uncertainties and external disturbances on the system performance reduced effectively and robustness of the system improved. The adaptive sliding mode controller is designed so that the practical system can track the state of the reference model. The asymptotically stability of the adaptive sliding mode control system proved based on the Lyapunov stability theory.
