研究車輛主動空氣懸架的控制問題，在車輛主動空氣懸的常規(guī)PID控制器的基礎(chǔ)上，運用模糊推理對常規(guī)PID控制器進(jìn)行參數(shù)在線修訂，設(shè)計了基于單輪車輛主動空氣懸架的Fuzzy-PID控制器，并對Fuzzy-PID控制的單輪車輛主動空氣懸架進(jìn)行Matlab建模和仿真試驗。仿真結(jié)果表明，與車輛被動空氣懸架、常規(guī)PID控制的車輛主動空氣懸架相比，F(xiàn)uzzy-PID控制的車輛主動空氣懸架可大大降低車身加速度和懸架動行程，提高車輛乘坐舒適性和操縱穩(wěn)定性，具有良好的魯棒性，從而驗證了Fuzzy-PID控制器的有效性和實用性。

　　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.
