Research on Sensor-Less Vector Control System of PMSM Based on MRAS

摘要

Based on the model reference adaptive system (MRAS), this paper makes a research on sensor-less vector control system of PMSM. The basic principle of MASR is analyzed, and the MRAS speed identification system of permanent magnet synchronous motor is designed. The control system model is simulated and analyzed based on MATLAB. The results show that the system tracks the motor speed accurately, and it has better dynamic performance and strong robustness.
