Abstract
This research focuses on implementing a group of control techniques to enhance the performance of Active Suspension System for different vehicle{u2019}s models under the presence of various road profiles. Linear and nonlinear mathematical models of quarter and half vehicle and a linear model of full vehicle are presented. PID controller is used for the linear models and Feedback Linearization control is used for the nonlinear models whereas Fuzzy Logic controller is used for both the linear and nonlinear models. Particle Swarm Optimization is the tuning method for the provided controllers. MATLAB/SIMULINK software is used for simulation which is based on the mathematical models. A comparison between the behavior of passive and active suspensions is demonstrated. Active suspension shows a significant enhancement compared to passive suspension
