A Rotor Position and Speed Observer for Permanent Magnet Motor with Non Sinusoidal EMF Waveform
(Institute of Electrical and Electronics Engineers, 2005-05)
A new nonlinear reduced-order observer to estimate the rotor speed and position for permanent-magnet motors, with arbitrary electromotive force (EMF) waveform, is presented. The proposed observer is suitable for the ...
Mechanical Sensorless Speed Control of Permanent Magnet Motors Driving an Unknown Load
(Institute of Electrical and Electronics Engineers, 2006-04)
A new sensorless scheme for high-performance speed control of permanent-magnet ac motors (PMACMs) driving an unknown load is proposed. This scheme uses an extended nonlinear reduced-order observer to estimate the induced ...
Power Flow Maximization in Permanent-Magnet Generators
(Institute of Electrical and Electronics Engineers, 2014-02)
The main hypothesis proposed in this paper is that by controlling the harmonic and zero-sequence components of the current in nonsinusoidal permanent-magnet synchronous generators (PMGs), additional energy can be obtained, ...
