Abstract
In modern industrial control system, permanent magnet synchronous motor is widely favored because of its high efficiency and high performance, but its control performance largely depends on the accuracy of the motor parameters. Therefore, the research of PMSM parameter identification strategy has important theoretical significance and application value. The aim of this research is to develop an accurate and efficient parameter identification method to improve the precision of motor control. The key parameters of PMSM, such as stator resistance, inductance and permanent magnet flux linkage, can be identified effectively under various working conditions, and the identification accuracy is significantly higher than that of traditional methods. The strategy also has good real-time performance and robustness, and can adapt to various dynamic changes during the operation of the motor. The PMSM parameter identification strategy proposed in this study shows significant advantages in improving the motor control performance. The precise identification of motor parameters provides a strong support for the high-performance control of the motor, and also provides an important reference for the optimal design of the motor system. This research not only provides a new idea and method for the parameter identification of permanent magnet synchronous motor, but also makes a positive contribution to the technical progress in the field of motor control.
