Adaptive Control Strategy for PMSM Current Loop Based on Parameter Identification

This study explores the importance and impact of current loop controller parameters in permanent magnet synchronous motor control systems. Parameter variations during motor operation, such as changes in temperature and operating current, can directly affect the control performance of the current loop and the overall stability of the system. This underscores the critical role of real-time and accurate motor parameter acquisition in current loop control to enhance controller dynamic performance and system stability. On the other hand, adaptive control methods offer a robust strategy to effectively handle variations in system parameters and external disturbances, demonstrating their value and extensive application potential in practical scenarios. Therefore, conducting research on adaptive control strategies for permanent magnet synchronous motors based on precise system parameters is of practical significance.
