| Abstract: | Parameter estimation method (based on block pulse function and least square method) applicable to virtual test system of a permanent magnet DC motor was discussed. Electromechanical parameters of the motor was obtained through parameter estimation. Physical parameters, dynamic and static characteristics of the motor were obtained from their function relations with the electromechanical parameters. Finally, fault detection and diagnosis were conducted. It was shown that the system possesses powerful and self contained test functions. |
