汽车悬架是车身与车轮之间的传力连接装置。运用MATLAB/Simulink建立仿真模型,应用模糊理论在线调整比例系数改进单神经元PID控制并设计控制器,进行三种工况下的仿真验证。结果表明:控制策略可行且控制器有较强的鲁棒性,进一步改善了汽车行驶的平顺性。
Car suspension is the force transmission between the body and the wheel connecting device. The simulation model is established by using MATLAB / Simulink. The fuzzy theory is used to adjust the proportional coefficient online to improve the single neuron PID control and design the controller. The simulation is validated under the three conditions. The results show that the control strategy is feasible and the controller has strong robustness, which further improves the ride comfort of the vehicle.
