| Abstract: | The hydraulic active suspension control design based on quarter car model considering the dynamics of the hydraulic actuator was addressed, which uses a combination of optimal control and nonlinear backstepping techniques. The simulation results show that the car has safe maneuverability and well passenger comfort in different road conditions by using the proposed controller. |
