车辆悬架Fuzzy-PID控制器设计方案

　　研究车辆主动空气悬架的控制问题，在车辆主动空气悬的常规PID控制器的基础上，运用模糊推理对常规PID控制器进行参数在线修订，设计了基于单轮车辆主动空气悬架的Fuzzy-PID控制器，并对Fuzzy-PID控制的单轮车辆主动空气悬架进行Matlab建模和仿真试验。仿真结果表明，与车辆被动空气悬架、常规PID控制的车辆主动空气悬架相比，Fuzzy-PID控制的车辆主动空气悬架可大大降低车身加速度和悬架动行程，提高车辆乘坐舒适性和操纵稳定性，具有良好的鲁棒性，从而验证了Fuzzy-PID控制器的有效性和实用性。

　　Abstract:

　　We make a study of the control on vehicle active air suspension. On the foundation of conventional PID controller for vehicle active air suspension，we make a on-line parameter-revise to conventional PID controller by using Fuzzy reasoning and design Fuzzy-PID controller based on single wheel active air suspension. Using matlab/simulink module， we make modeling and simulation of single wheel active air suspension. The simulation results show that， Comparing with single wheel passive air suspension and single wheel active air suspension with the conventional PID controller， aingle wheel active air suspension with the Fuzzy-PID controller can improve vehicle ride comfort ，handling stability， and have good robustness.
