摘要: This paper presents a hybrid, motion sensorless control of an Axially Laminated Anisotropic (ALA) Reluctance Synchronous Machine (RSM). The zero and low speed method is saliency based High Frequency Signal Injection technique (HFSI) that uses the motor itself as resolver. second on state observer incorporating “active flux” concept used to deliver RSM rotor position information for medium high range. Even if both methods perform successfully in separate regions, estimation two algorithms combined sensor fusion improve performance at very speeds. Experimental results validate proposed strategies.
