【 摘 要 】

With the extensive application of permanent magnet synchronous motor in the new energy vehicle industry, the requirements of manufacturers for motor speed control and torque response performance are also more stringent. However, the inductance parameters of the motor will change in real time as the current changes, which will affect the responsiveness and stability of the control. Based on the simplest PI regulator, this paper presents a method to identify the parameters of permanent magnet synchronous motor (PMSM) and uses this parameter to improve the regulator.
