In this paper, in order to improve the ride comfort and road holding for a semi-active suspension system,a PID controller-based Genetic Algorithm (GA) is proposed. For this paper, two road scenarios,including bump road, roughness, and bounce sine sweep road, have been utilized. The collaborativesimulation platform based on the CarSim and MATLAB/Simulink is developed. The simulation resultsillustrate the advantage of the proposed robust optimal control strategy for the suspension system. Also,an attempt has been made to optimize suspension parameters such as ride comfort and road holding inthis simulation with GA.
