Despite two decades of massive strides in research and development on control strategies
and their subsequent implementation, most books on permanent magnet motor drives still …

A back-electromotive force-based sensorless technique for surface-mounted permanent
magnet synchronous motor drives is considered in this paper. The model of the observer is …

The rotor position of a salient-pole permanent-magnet synchronous machine (PMSM) at
standstill or rotating at low speed is often estimated by measuring the responses on high …

This paper investigates a starting procedure of rotational sensorless permanent magnet
synchronous motor (PMSM) in the rotating condition, which is suitable for some applications …

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 …

Persistent, transient and, very recently, pulse width modulated voltage excitation are
employed to track saliency of IPM machines, aiming at estimating rotor position. In this paper …

This paper presents an improved rotating restart method for a sensorless permanent magnet
synchronous motor (PMSM) drive system using repetitive zero voltage vectors. To restart the …

Rotor position information is necessary to control PMSM (Permanent Magnet Synchronous
Motors). Extracting rotor position information using physical position sensor presents several …

Motor current derivatives contain useful information for control algorithms, especially in
sensorless electric drives. The measurement of motor current derivatives in electric motors …
