摘　　要：从伺服机构机理建模开始,通过发动机负载模型辨识,搭建伺服机构和负载的仿真模型,通过实验验证了模型的准确性,并以此为基础,对反馈一路故障条件下的系统性能进行仿真,通过实验验证了故障仿真下的动态和静态系统特性。Begin with servomachanism modeling and motor model identification,the model was made and verified accurately by the experiments.Based on the model and one of the position sensors fault,the dynamic and static character of the system was simulated and verified by the experiments.
