The purpose of this paper is to investigate the performance of an active suspension of a quarter car model using Linear Quadratic Regulator (LQR) control and Proportional Derivative Integral (PID) control. Dynamic model of used in this study is a linear model. It can capture basic performances of vehicle suspension such as body displacement, body acceleration, wheel displacement, wheel deflection, and suspension travels. Performance of suspension system is determined by the ride comfort and vehicle handling. Ride comfort can be measured by observed the car body displacement while vehicle handling performance can be observe the wheel displacement output. Other parameters that will be observed are suspension travel and wheel deflection. Two types of road profiles are used as input for the system. LQR and PID control strategy performance will be observed depend on the changes of the road surface. Simulation is based on the mathematical model by using MATLAB/SIMULINK software. Results show that performance of body displacement and wheel displacement can be improved by using LQR and PID control scheme.
