This paper delivers findings on optimal control studies of two degree of freedom quarter car model. Nonlinear active suspension quarter car model is used which considering the strong nonlinearities of hydraulic actuator. The investigation on the benefit of using Sliding Mode Control as force tracking controller with the utilization of Particle Swarm Optimization is done in this paper. The controller is designed to improved trade-off performance between ride comfort and road handling ability. Comparison between proposed controller with PID control and conventional suspension system showed that performance of the proposed controller is significantly improved. Results illustrated via simulation runs using MATLAB.
