This work described in the paper to show the implementation of Proportional Integral (PI) controller, Genetic algorithm based PI (GAPI), and Particle swarm optimization based PI (PSO-PI) for a Quarter Car System. The trip comfort is developed by means of the decrease of the body acceleration caused by the car body, due to the smoothness of the road. This paper tells about the model and controllers used in the study and discuss the vehicle response results. In the conclusion, a comparison of PI, GA-PI, and PSO-PI is shown using MATLAB simulations.
