Owing to the competitive advantages of cost reduction, system downsizing, and reliability
enhancement, position sensorless control methods for permanent magnet synchronous …

The development of electrostatic rotating machines for macroscale power conversion has
been largely sidestepped, given the uncertainty of its capabilities and place in the …

In this paper, a novel square-wave-type carrier signal injection method using zero-sequence
voltage is proposed for sensorless control of permanent-magnet (PM) synchronous machine …

Low resolution Hall-effect sensors have been commonly applied in PMSM drives for the
reason of cost and volume. Generally, rotor speed and position are estimated inaccurately …

This paper focuses on the observer-based methods for induction machine sensorless drive.
It is well known that the use of speed observer is limited at a very low stator frequency due to …

Sensorless control is a common control method used in variable speed drive applications
with permanent magnet synchronous machines (PMSMs). In these drive systems, phase …

This paper presents encoderless model predictive control scheme with time-varying sliding
mode observer for a complete wind turbine system. The wind turbine system consists of a …

Self-sensing control at zero and low speed has been widely implemented and studied by
many researchers. This technique is based on injecting a high-frequency voltage or current …

Back-electromotive force (back-EMF) self-sensing is commonly used in induction machine
(IM) drive systems for its maintenance cost and safety considerations. In recent years …

This paper analyzes the angle estimation errors for signal injection based sensorless control
with an analog bandpass filter (BPF). The analog BPF has been used to reduce the level of …
