摘要
为了提高汽车的舒适性和安全性,针对汽车磁流变半主动悬架的控制策略进行研究;首先采用模糊理论算法设计控制器对其进行控制;其次,在Simulink中对模糊控制系统进行仿真,验证控制策略的可行性。仿真实验结果表明:此种模糊控制的半主动悬架能够有效地提高车辆悬架的整体性能。与被动悬架相比,在随机路面激励情况下磁流变半主动悬架的车身加速度和悬架动行程均有明显提升。
In order to improve comfort and safety of automobile,the control strategy of automotive MR semi-active suspension was studied by using the theory of fuzzy algorithm designed controller so as to control it.The fuzzy control system was simulated in the simulink,and the feasibility of the control strategy was verified.The simulation results show that the overall performance of the vehicle suspension can be effectively improved through the fuzzy control semi-active suspension.Compared with the passive suspension,under the condition of random road excitation,the body acceleration and suspension dynamic schedule of MR semi-active suspension have obvious improvement.
