Abstract

The purpose of this paper is to present a modeling and control of the active suspension system using Conventional Sliding Mode (SMC) and Proportional Integral Sliding Mode Control (PISMC) techniques. The objective of designing the controller for the car suspension system is to reduce the traditional design as a compromise between ride and handling by directly controlling the suspension forces to suit the road and driving conditions. In this paper a new mathematical model is presented which will give a much more complete mathematical representation of hydraulically actuated suspension system for the half car model. In order to achieve the desired ride comfort and road handling and to solve the mismatched condition, a conventional sliding mode control and a proportionalintegral sliding mode control will be utilized to deal with the system uncertainties. Mathematical analysis for reach ability and stability of both controllers will be derived. Finally, a simulation of a half-car hydraulically actuated active suspension system will be carried out using Matlab/Simulink software. Some comparisons and analyses will be made from the simulation results
