【摘要】 用AMESim软件建立了1/4车体二自由度的主动悬架模型,在MATLAB/Simulink中设计了模糊控制的主动悬架,利用AMESim和MATLAB进行了联合仿真。并与基于传统数学模型的主动悬架的仿真结果进行了比较,结果表明两者的车身加速度仿真曲线形状基本上是一致的,与被动悬架相比降低了垂直加速度,有效提高了乘车舒适性,控制策略是可行的。随着被控制对象的复杂化,动力学方程的建立越来越困难,这种联合仿真技术开创了一条效果很好而又不复杂的仿真新途径。更多还原

【Abstract】 The vehicle’s active suspension based on fuzzy control is built and co-simulated with AMESim and MATLAB. Compared with the active suspension based on math model, the result shows that the acceleration curve basically is the same, and the control strategies are reasonable. Compared to passive suspension, the active suspension fuzzy control based on AMESim can reduce the bodywork acceleration. The dynamics equation and transfer function aren’t needed with the co-simulation method. The method offers a new though to the simulation of control system of complex mechanism.更多还原
