Performance Comparison of Semi-Active Suspension and Active Suspension System Using MATLAB/ Simulink

Abstract

In this paper a brief introduction to MR damper and its various types with a brief introduction to vehicle primary suspension system is presented along with analysis of a semiactive suspension system. Isolation from the forces transmitted by external excitation is the fundamental task of any suspension system. The heart of a semi active suspension system is the controllable damper. In this paper, the ride and handling performance of a specific vehicle with passive suspension system is compared to semiactive suspension system. The body suspension wheel system is modeled as a two degree of freedom quarter car model. Simulation is carried out using MATLAB/Simulink. The developed design allows the suspension system to behave differently in different operating conditions, without compromising on road-holding ability. Controller has been developed for semi active suspension. The result shows improvement over passive suspension method
