Method of DFIG Cooperating with SVG to Suppress Low-Frequency Oscillation in Power Systems

Zhongguo dianli, 2020
With the increasing penetration of wind power, when the power system is insufficiently damped, low-frequency oscillations are likely to occur. Doubly fed induction generation (DFIG) can decouple the control of active and reactive power, which helps ...

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.
