摘要
文章采用了一种直接把空气弹簧的非线性力放入系统模型中进行分析和计算的方法,在非线性模型上分别施加一般模糊控制和参数自调整模糊控制,并比较两种控制方法对车辆行驶平顺性的影响;运用Mat-lab/Simulink软件对系统进行平顺性分析,其结果发现运用非线性方法更能真实反映车辆在实际行驶中的振动响应情况,而施加参数自调整模糊控制较一般模糊控制能进一步改善车辆行驶平顺性。
A method of putting the non-linear force of the non-linear suspension system into the system model directly so as to carry out analysis and calculation is adopted,the methods of the usual fuzzy control and the parameter adjustable fuzzy control are applied to the non-linear model respectively, and the effects of the two control schemes on the riding characteristics of the automobile are compared. The software Matlab/Simulink is used to analyze the riding characteristics of the automobile with the air-spring non-linear suspension system. Simulation results show that the non-linear model of the suspension system can represent real performance of vibration response, and that the parameter adjustable fuzzy control may improve the riding characteristics further than the usual one.
