| 摘 要： | 为改善汽车的平顺性,将模糊控制算法引入半主动悬架,对其控制系统进行研究。首先以四自由度汽车半主动悬架为研究对象建立了其数学模型与仿真模型;在Matlab中利用模糊逻辑工具箱Fuzzy Toolbox设计了半主动悬架模糊控制器;在此基础上,利用Matlab/Simulink软件搭建半主动悬架模糊控制系统并在白噪声路面及阶跃路面信号激励下进行仿真试验。实验结果表明,所设计的模糊控制器可以有效改善汽车的平顺性并提高汽车的行驶安全性。

| Abstract: | In order to improve the ride comfort of vehicle, the fuzzy control algorithm is introduced to the semi-active suspension and its control system is studied.The mathematics and simulation models of four DOF (Degree of Freedom) vehicle semi-active suspension are built, and the fuzzy controller for semi-active suspension is designed by using the fuzzy logic toolbox of Matlab;On this basis, the semi-active suspension fuzzy control simulation system was built by Matlab/Simulink, and the simulation test was carried out with the white noise road surface and the step road input.The results showed that the designed fuzzy controller can improve the ride comfort and driving safety of the vehicle effectively. |
