| 摘 要： | 建立了1/4主动悬架模型,设计出自适应模糊增益调节PID控制器,参照系统在时频两域中的响应情况对PID的控制参数进行整定,并使用模糊控制器对PID的控制量加以修正.对被动悬架、单纯PID控制的悬架和自适应模糊PID控制的悬架分别施以阶跃信号激励和积分白噪声信号激励进行仿真.结果表明,自适应模糊PID控制算法具有较好的控制效果和鲁棒性.

| Abstract: | A-quarter active suspension model was established,and a plus-adjust self-adaptive Fuzzy-PID controller was designed. The parameters of the controller were fixed with the responses of the system in time domain and frequency domain. A fuzzy controller was used to modify the force output with the PID controller. Step signal and white noise signal were imposed on passive suspension, PID controlled suspension and self-adaptive Fuzzy-PID controlled suspension respectively. The simulation results have shown that the self-adaptive Fuzzy-PID control arithmetic have better performances and is robust. |
