摘　　要：针对电控空气悬架车辆车身高度调节过程中出现的振荡和偏离设定目标高度的问题,建立了车身高度调节过程的数学模型,设计了车身高度调节的模糊PID控制器并应用Matlab/Simulink软件进行了仿真。结果表明:应用该控制方法可以有效地解决上述问题,使车身高度精确到达设定的目标高度。In the process of electronic air suspension vehicles body height adjustment, the body height will have oscillation and can not reach the target height. To overcome these problems, the mathematical model of the body height adjustment process was built and the fuzzy-PID controller was designed. And simulations were made in Matlab/Simulink. The simulation results demonstrate that the application of fuzzy-PID control can effectively solve the above problems and make the body height precisely reach the target height.
