Abstract
AbstractThe high‐performance motor control relies on the accuracy of the interior permanent magnet synchronous motor (IPMSM) parameters. In order to automatically identify the electrical parameters of IPMSM, an online parameter identification method has been developed based on robust adjustable and double tracking error to improve the identification accuracy of IPMSM parameters, which has been verified by both simulation and experiment. Also the torque closed loop was used to check the accuracy and reliability of the parameter identification. On the one hand, the simulation results show that the identification error was less than 10%, decreasing the response time and enhancing the robustness of parameter identification. On the other hand, the experimental results derived from the TC1782‐based platform verify the effectiveness and robustness of the proposed method, above all results indicating that the present identification algorithm has excellent performances of IPMSM drives system and engineering practicability.
