In order to make the active hydraulic suspension system to adaptive the ground. Taking the asymmetric valve controlled hydraulic cylinder as actuators, a six wheels hydraulic active suspension was designed. It is difficult to analysis of the six wheels system. So this paper established the single wheel’s mathematical model to instead analysis of the whole system, designed QFT (Quantitative Feedback Theory) controller which can be a solution to the system robustness, researched the hydraulic active suspension system. The results show that it is good for tracking performance of the hydraulic cylinder which taking the asymmetric valve controlled as actuators, system responses timely and the controller can meet the controlling requirements. This hydraulic active suspension system can improve off-road performance of engineering vehicles.
