| Abstract: | A novel vibration damping control technique was introduced into vehicle semi-active suspension system based on EHA. The principles of the semi-active systems based on EHA were introduced both a quarter vehicle model and road input model were built, and a hybrid control strategy of sky-hook control and ground-hook control was designed for the semi-active system. The semi-active system was simulated by the software Matlab/Simulink. The result illustrates, excited by random road input, using the hybrid control strategy can improve handling and stability of vehicles, make the performance of vehicles better. |
