以空气悬架系统为研究对象，建立了半主动空气悬架的1/4车辆模型及白噪声的路面激励模型，将模糊控制理论和PID控制方法结合起来设计模糊PID控制器，并利用Simulink对建立的动力学模型进行平顺性仿真分析。从最终的结果可以得到结论：与传统PID控制的空气悬架相比，模糊PID控制的半主动空气悬架能更好地提高车辆的行驶平顺性。

Based on the research of the air suspension system, the 1/4 vehicle model of the semi-active air suspension and the white noise of the road excitation model were established. Combining fuzzy control theory with PID control method, the fuzzy PID controller was designed. Based on MATLAB/Simulink software, the model of riding comfort was simulated and analyzed. From the final result, the conclusion was drawn that the semi-active air suspension with the fuzzy PID controller as compared with the traditional one, can much better improve the riding comfort of the vehicle.
