TL;DR: In this paper, the performance limits of carrier-signal-injection-based sensorless control methods were studied. But the analysis focused on three key performance metrics: 1) the accuracy, 2) the bandwidth, and 3) the stability of the estimated position.

TL;DR: In this paper, the design and tuning of selective harmonic current regulators is addressed, with a focus on their stability analysis and transient behavior, and the presence of multiple current regulators working in parallel can create unwanted couplings with the fundamental current regulator, which can result in a deterioration of APF current control.

TL;DR: In this paper, a strategy for the coordinated operation of the inverters without the need of communications or pre-established roles is proposed for islanding detection using high-frequency signal injection in microgrids with multiple parallel-connected inverters.

TL;DR: Airgap flux monitoring is investigated as an alternative for providing reliable identification of rotor and load faults in PMSMs and it is shown that the proposed method provides reliable on-line identification of the faults for cases where conventional spectrum analysis based methods fail.

TL;DR: This paper analyzes the various methods for current sampling and measurement in AC drives and power converters with particular attention paid to the performance and limits of synchronous sampling.
