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 ...
Vector Control Applied to Mitigate the Electromagnetic Torque Ripple in Doubly Fed Induction Generator
(2021-01-01)
This paper proposes a novel Vector Control topology for stator current harmonic mitigation, due to the grid voltage harmonic content, focusing on mitigating the torque undulations in the Doubly Fed Induction Generator. The ...
