高周波電圧・電流を用いた外乱オブザーバによるシンクロナスリラクタンスモータの位置・速度センサレス制御

Synchronous reluctance motors (SynRMs) are characterized by their sturdiness, and several sensorless control methods of SynRMs have been proposed. In their methods, flux is estimated and the rotor position is estimated from the flux. The induced voltages for flux estimation are small at low speed. In this paper, new position estimation method is proposed using the disturbance observer based on high frequency currents. Simulation results show that the proposed system is very useful.
