摘　　要：采用精度较高的Bouc-Wen模型对磁流变减振器建模,建立了包含减振器非线性动态特性的1/4车辆模型。为了解决Bouc-Wen模型给磁流变半主动悬架系统带来的非线性,通过Takagi-Sugeno模糊建模对磁流变半主动悬架系统的非线性项进行局部线性化,并利用并行分布补偿(PDC)方法求取系统的控制器。设计了与Bouc-Wen模型相结合的磁流变半主动悬架控制系统,系统仿真结果和硬件在环仿真试验验证了该方法的有效性。A one-quarter-vehicle semi-active suspension based on Bouc-Wen model of MR damper was proposed. A Takagi-Sugeno fuzzy control method which includes the actuator nonlinear dynamics was presented in this study for the control of the nonlinear semi-active suspension system. Due to system＇s fuzzy nature, the controller gain was applied via Parallel Distributed Compensation （PDC） through a static state feedback controller for each linear subsystem. The research improves that an MR damper, represented by the Bouc-Wen model, is suitable for control purposes. The numerical simulation is carried out, which confirms the controller proposed is feasible and effective.
