摘　　要：随机振动试验中,控制方法的选取对试验结果具有重要影响。本文基于高阶微分器(HOD)与误差微分控制(EDC),设计了一种HOD-EDC的无模型随机振动控制方法。通过MATLAB Simulink建立仿真模型,与传统的对数域控制(LDC)频谱均衡控制方法进行对比,验证HOD-EDC的控制表现。通过改变被试系统的参数,验证HODEDC无模型控制方法对不同被试系统的控制能力。仿真结果表明,HOD-EDC无模型控制方法受到长时间的误差累积影响小,均衡速度快,对于不同参数的被试系统,都能表现出良好的控制稳定性。In the random vibration test,the selection of control method has an important influence on the test results.Based on the High Order Differentiator(HOD)and Error Differential Control(EDC),a model-free random vibration control method of HOD-EDC is designed in this paper.The simulation model is established by MATLAB/Simulink,and the performance of HOD-EDC is verified by comparing with traditional LDC spectrum equalization control method.By changing the parameters of the system,the control ability of HOD-EDC control method to different system is verified.The simulation results show that the model-free control method of HOD-EDC is not affected by long-time error accumulation and has fast response speed.
