A Novel Sliding Mode Control Algorithm for an Active Suspension System Considering with the Hydraulic Actuator

The suspension system has the role of regulating and extinguishing oscillations in vehicle. To improve stability comfort, active is proposed to replace passive system. There are many algorithms used for control, such as PID, LQR, Fuzzy, etc. Among them, nonlinear control method which uses SMC algorithm gives a stable performance. This research proposes use operation equipped with quarter dynamics model. process linearization hydraulic actuator presented paper. As result simulation, values displacement acceleration sprung mass were significantly reduced when vehicle controlled by algorithm. controller established this paper provides situations. Therefore, vehicle's smoothness comfort have been improved. In future, intelligent can be combined efficiency controller.
