Abstarct: The thesis of a new plan for the control of vehicle active suspension system is used with feedback resistant with robust integral of the sign of the error. It very well could be the dynamic behavior of the road disturbance suspension control .system suspended for controller design is intended, active suspension system is with a one- quarter model and considering nonlinear effects of road and hydraulic actuator. Robust integral of the sign of the error, more for non-linear systems, despite uncertainties and uncertainties, the model used and studied in this thesis with Coefficients constants and the non-linear ,the non-linear in nature because of the road disturbances with uncertainties and uncertainty. The controller control with less effort and more importantly, having at least chattering of the other controller made so far on the suspension have been superior. Then, this controller with the sliding mode controller that one of the best control in the field of non-linear systems with uncertainty, compare and claim superiority with graphs of the simulation is fixed. Stability of controller robust integral of the sign of the error, studied and correct stability control with stability analysis and simulation results is confirmed.
