Automotive suspension system with an analytic fuzzy control strategy

According to the model of vehicle suspension, a novel fuzzy control method based on adaptive technology is applied to active control of automotive suspension system. An analytic fuzzy control algorithm is advanced in order to improve the riding comfort and handling safety of automotive. Because the algorithm can adjust the rectification factor of fuzzy controller, it not only can reflect the advantage of fuzzy logic in nonlinearity system but also can improve the disadvantage of common fuzzy control method strongly depending on the experience. For the sprung mass acceleration, the dynamic tyre load and the dynamic deflection of suspension system, the simulation results show that the analytic fuzzy control strategy has obvious effect on the vibration control of automotive suspension system.
