IET Generation, Transmission & Distribution, 2021 In recent years, methods for loadability determination based on real‐time measurements have been proposed for long‐term voltage stability scenarios. One of these methods corresponds to the reduction of the complete system into a basic Thevenin equivalent

Reduction of total harmonic distortion in power inverters [PDF]
, 2005 The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and modulation of the dc bus voltage.

Development of a state feedback controller for the synchronous buck converter [PDF]
, 2005 A digital control algorithm for a current-mode (CM) and a voltage-mode (VM) synchronous buck converter (SBC) is developed. In both cases, the design leads to a stable controller, even for a duty cycle larger than 50%.

Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.
