Haifa Souilem, Sonia Mahjoub, Nabil Derbel . Sliding Mode Control of Half-car Active Suspension. International Journal of Computer Applications. 155, 14 ( Dec 2016), 1-6. DOI=10.5120/ijca2016908524
The purpose of the sliding mode controller for a vehicle suspension system is to reduce the discomfort sensed by passengers which arises from road roughness and to increase the ride handling asso- ciated with the pitching and rolling movements. This necessitates a very fast and accurate controller to meet as much control objec- tives, as possible. This paper deals with introducing a new technique such as Propor- tional Integral Sliding Mode controller(PISMC), sliding mode con- troller(SMC) and PID approaches to Half-Car Active Suspension to design a stability to meet the control objectives. The advantage of this controller is that it can handle the nonlinearities faster than other conventional controllers. The approach of the proposed con- troller is to minimize the vibrations on each corner of vehicle by supplying control forces to suspension system when travelling on rough road. Simulation results and a comparison with a calssical PID con- troller are presented and discussed. We studied the stabil- ity of the three used controllers in the presence of distur- bances. A good performance for the sliding mode controller (SMC) is achieved in simulation studies despite the disturbances.
