Backstepping controller and Sliding Mode controller are designed to control the active, nonlinear half-car suspension. By comparing the performance between Backstepping, Sliding Mode, PID and passive suspension (controllerless suspension) to find the best control method. Performance considerations are: ride comfort, grip, suspension space and force saturation. Matlab Simulink is used to simulate and produce results under a given pavement input. The results show that the Sliding Mode controller gives the best results. Then there are Backstepping and PID controllers. The suspension using the controller gives better results than the passive suspension.
