摘　　要：为提高气动伺服系统的行程与精度,设计了一种新型的使用金属波纹管作为单极驱动机构的气动伺服系统,并建立了新型气动伺服系统的动力学模型。所建模型采用传统的PID控制,通过MATLAB软件Simulink仿真研究了控制效果,所得仿真结果能较好的跟随输入信号。根据所建模型搭建试验平台,使用Lab VIEW作为上位机采集数据得到波形,所得试验结果与仿真结果基本一致,验证了仿真模型的有效性。In order to improve the precision of the pneumatic servo system,we design a new type of pneumatic servo system used metal bellows as the single driving mechanism. The dynamic model of the new pneumatic servo system driven by the metal bellows is established. PID control effect is studied through Matlab simulation and the simulation results can follow the input signal very well. We build a test platform based on the simulation model and use the software Labview to collect data and get waveform,and findthat the test results are consistent with the simulation results,which verifies the validity of the simulation model.
