摘要
Abstract
A novel sensorless control method of permanent magnate synchronous motor(PMSM)under zero-low speed range based on high frequency signal injection into the stator flux was presented. By using the estimated electromagnetic torque and stator flux linkage,the load angle and the position error angle could be observed. Finally, the rotor position and speed could be estimated with a phase-locked loop principle(PLL). Theoretical analysis and the simulation were carried out. The result shows the new method can observe the rotor position and speed exactly at low speed,and achieve a good dynamic performance.关键词
