| 摘 要： | 通过建立某型汽车主动悬架系统的动力学方程和路面输入模型,融合PID控制和模糊控制的优点,设计了主动悬架模糊PID控制策略.在Matlab/Simulink环境中对此控制器进行的仿真结果证明,相对传统的被动悬架,本方法在降低乘员座椅垂直加速度、改善行驶平顺性和乘坐舒适性方面效果良好.

| Abstract: | This paper applied the excellent mixture of PID and fuzzy logic theory to design the fuzzy-PID logic controller of the active suspension by the establishment of dynamics model of an automobile active suspension and road input model;simulates in the environment of Matlab/Simulink and compare the simulation results with the conventional passive suspension and the suspension with a PID controller.The simulation results demonstrate that the suspension with the fuzzy-PID logic controller can effectively decrease the passenger vertical acceleration and vehicle's riding performances. |
