High-performance sensorless synchronous reluctance drives (SynRel) require self-commissioning during the drive start-up to identify a magnetic model (flux maps) of the machine taking into account the saturation and the cross-saturation phenomena. Generally, the stator flux linkage is calculated based on the stator voltage integration. Inverter nonlinear voltage errors mainly caused by dead-time and on-state voltage drops deteriorate the voltage estimation that decreases the flux estimation accuracy. This paper presents a comprehensive study of inverter nonlinearity effects on flux maps identification and its compensation strategy.
