Simulink Modeling of Dual-Loop Speed Control for Permanent Magnet Synchronous Motors

This study designs a dual-loop speed control system for PMSMs on the Simulink platform, employing vector control with SVPWM to decouple current and speed. The model integrates the PMSM, coordinate transformations, PI controllers, and inverter. Simulations show rapid speed tracking with steady-state error under 5% and recovery time below 0.1 s under load disturbances, validating the control strategy and model accuracy.
