摘　　要：本文建立了电磁激振器的机电耦合动力学模型,给出了面向实时控制需求的鲁棒控制器设计方法。通过试验对电磁激振器的模型参数进行了识别,通过试验结果与模型结果的对比验证了识别方法的有效性。基于CRIO搭建了快速控制原型验证试验平台,分别开展了空载作用下的加速度、负载作用下的动态力实时控制试验,验证了方法的有效性。Electromechanical coupling dynamic model is established, and a robust control design method for real-time control requirements is presented in this paper. The model parameters of electromagnetic exciter were identified by test data. The effectiveness of the method was verified by comparing test result and model result. Based on CRIO, verification platform of rapid control prototype was constructed to carry on real-time control test. Finally, unload and load control test of electromagnetic exciter demonstrated the effectiveness and accuracy of present design method.
