高加速气浮系统的半仿真模型辨识

摘要

In this paper,a half simulation environment have been constituted with Coplay drive,CME2 software,air suspen-sion motion platform,PMAC motion control card and MATLAB software components;for high acceleration motion platform air suspension system model identification research,and the identification of the model Simulation in simulink,with the system's step response signals at different results were compared to verify the correctness of the identification model.%利用Coplay驱动器、CME2软件、气悬浮运动平台、PMAC运动控制卡以及MATLAB软件组成的半仿真环境，对高加速气悬浮运动平台进行系统模型辨识研究，并对所辨识模型在Simulink中进行仿真，与系统真实阶跃响应在不同信号下的结果进行对比，来验证所识别模型的正确性。结果表明，该方法切实可行，同时该方法具有实时性、可进行大量运算、添加高级算法等优点，为高阶高动态系统的精确控制提供了研究依据。
