| Abstract: | A method of high frequency signal injection was introduced in the permanent magnet synchronous motor(PMSM) sensorless control system.The double-closed loop model was built with vector control and space vector pulse width modulation(SVPWM).The rotor position observer was founded by heterodyning to detect the information of torot position.System control model was constructed under Matlab/Simulink environment,the analysis of system proved that the method can estimate rotor information accurately and is able to... |
