| Abstract: | In order to solve motor fault on-line diagnosis,first the system dynamic model parameters for a motor by the on-line least square estimation is performed,and changes in the system model parameters are detected and then the model-based parameter estimation method is used to obtain fault detection.According to the diagnosis equations for the model parameters,the system failure factors can be identified,and combined with application examples,it proves that the method is feasible and effective. |
