The impact of electromagnetic interference (EMI) is an increasingly important aspect of the
performance of switching inverters. The challenges of managing EMI continue to grow with …

A traditional linear extended state observer (LESO) does not have enough capacity to
handle the rapidly-varying back electromotive force (EMF). This key weakness limits the …

To heighten the position estimation accuracy of sensorless control of interior permanent
magnet synchronous motor (IPMSM), an improved full-order sliding mode observer (FSMO) …

The extra acoustic noise caused by the high-frequency (HF) signal injection imposes
restrictions on its extensive applications for sensorless synchronous reluctance motor …

Accurate rotor position estimation is important to ensure the high-performance operation of
position sensorless permanent magnet synchronous motor (PMSM) drives. To suppress the …

Harmonics and drifts are found in the position estimation errors of high-frequency signal
injection (HFI) methods. To suppress the position estimation error, a hybrid active flux …

This article proposes a pseudo-random high-frequency triangular-wave current signal
injection (PR-HFTCI) based sensorless control scheme for synchronous reluctance motor …

The interturn short-circuit fault (ITSCF) is a common incipient fault for the permanent magnet
synchronous machine (PMSM) drive system. In recent years, the high-resolution ITSCF …

This article presents a position and speed estimation scheme based on the extended state
observer in the linear synchronous motor (LSM) drives for high-speed maglev application …

To improve the stability and accuracy of the estimated position using the conventional
sliding mode observer (CSMO) under low frequency ratio (LFR), this article proposes a …
