| 摘 要： | 对带有电流变液智能阻尼器的半主动汽车悬架系统设计了一种模糊PID控制器。将半主动悬架簧载质量的位移及其导数作为模糊控制器的输入，PID控制器的3个增益参数作为其输出，利用电流变液智能阻尼器的阻尼力可随电压变化的特性来使车身的振动降为最小。仿真实验给出了最优被动悬架、固定参数PID控制智能半主动悬架和模糊PID控制智能半主动悬架在不同路面激励情况下的响应曲线。

Fuzzy-PID Control for Automotive Semi-active Suspension with ER Damper |
| |
| Abstract: | A fuzzy-PID controller is designed for automotive semi-active suspension with electro-rheological(ER)damper.The inputs of the fuzzy controller are the deviation of the sprung mass displacement and its derivative,while its outputs are proportional,integral,and derivative gains of PID controller.Simulations are performed and the response curves in different road excitation are obtained for fuzzy-PID controlled semi-active suspension as well as for conventional PID controlled semi-active suspension and optimal passive suspension.The results demonstrate that the performance of fuzzy-PID controlled semi-active suspension is better than that of other two systems. |
