- Abstract
A sensor-less control method of permanent magnet synchronous motor (PMSM) based on sliding mode observer (SMO) is studied in the synchronous rotating reference orthogonal coordinate system in the work. The SMO is proposed under the synchronous rotating coordinate system and in which the sign function is replaced by saturation function in order to eliminate the chattering phenomenon. The rotor position and speed estimation can be obtained from the induced electromotive force (EMF) observed from SMO by using the phase locked loop (PLL), which can achieve the purpose of sensor-less control. The simulation results show that the system can accurately track the rotor position information in a real time and meet the needs of the actual motor control performance.
