摘要：
This paper analyses the stability margin of permanent magnet synchronous motor (PMSM) control system that uses a complex PI controller, specifically under high current conditions. Under high current conditions, the inductance of the motor sharply decreases. And if the bandwidth of the current controller is set high enough, stability issues arise. This paper examines the reasons for changes in system stability and proposes a parameter design method to enhance stability.
