Abstract
In this paper, a control law is developed based on the sliding mode control for electrohydraulic active suspension. The law is derived from simulation of hydraulic system, which contains valve and actuator dynamics.
Controller is designed in such a way that the displacement and acceleration (as two independent set points) to approach to zero. When the acceleration is controlled, the displacement deviates from set point, therefore new control approach has been developed. The input servovalve voltage is determined in such a way that, actuators apply required force to sprung mass in order to increase ride comfort. At first the dynamic equations for vehicle are derived. Sliding mode control is applied for derivation of control equations. Then the equations have been solved by simulink and finally the results have been presented.
