Electric drive without electrical and mechanical sensors is the critical obligation in most of
the industrial applications due to its user-friendly hardware, lower maintenance, low cost …

The anisotropy of a cage rotor is utilized to determine the angular position of the rotor in an
induction machine. The switching transients generated by a pulsewidth-controlled inverter …

In order to suppress the torque ripple of an open-end winding permanent-magnet
synchronous machine (OEW-PMSM), a q-axis current injection method is typically employed …

This paper addresses the sensorless speed and position control of induction motors using
high-frequency injection at zero and low frequencies. A novel algorithm is presented which …

This paper presents a new method for position estimation in shaft-sensorless ac motor
drives over the entire speed range, including zero frequency. The method is based on the …

This paper considers both flux and rotor position estimations for sensorless control of delta-
connected cage induction machines (IMs) at low and zero frequency operation. The …

This paper proposes a zero-sequence model-based sensorless control strategy for open-
winding permanent-magnet synchronous machine (OW-PMSM) with common dc bus. The …

Operation of model-based sensorless control of Alternating Current machines at low and
zero speeds is unreliable and can fail. To overcome the limitations of sensorless control at …

The sensorless control of induction machines, particularly for operation at low speed, has
received significant attention in recent years. To realize a field-oriented control of AC …

It has been well established in the literature that inverter nonlinearity effects afflict saliency-
based sensorless drives. The inverter nonlinearity leads to the generation of signals that …
