摘　　要：根据车辆系统动力学理论,建立了采用磁流变半主动悬架系统的装甲车辆的动力学模型。针对模糊控制过分依赖经验和控制精度不高的问题,提出基于规则的两级变论域模糊控制方法。研究不同车速和路况条件下磁流变半主动悬架系统的控制效果,并与被动悬架和传统模糊控制进行比较。研究结果表明:基于规则的两级变论域模糊控制方法能有效改善装甲车辆行驶的平顺性,控制效果明显优于传统模糊控制。A dynamics model for an armored vehicle with magneto-rheological（MR） semi-active suspension system is established based on the theory of vehicle system dynamics.Aiming at the problems of excessive dependence on experiences and relatively low control accuracy in conventional fuzzy control,a rule-based fuzzy control strategy with two-stage variable universe is proposed.The control effects of MR semi-active suspension at different vehicle speeds and road conditions are studied and compared with that of passive suspension and traditional fuzzy control.The results show that the control strategy proposed can effectively improve the ride comfort of armored vehicle with a control effect obviously superior to traditional fuzzy control.
