H2 controller design on engine rotor rotation
(2020)
This article exposes the implementation of the H2 controller, which is rare in the literature because it is a more robust control and not only errors but also disturbances that can affect the dynamics of the control system ...
Improved genetic algorithm for phase-balancing in three-phase distribution networks: A master-slave optimization approach
(2021-05-14)
This paper addresses the phase-balancing problem in three-phase power grids with the
radial configuration from the perspective of master–slave optimization. The master stage corresponds
to an improved version of the Chu ...
A Comparative Study on Power Flow Methods Applied to AC Distribution Networks with Single-Phase Representation
(2021-10-21)
This paper presents a comparative analysis of six different iterative power flow methods applied to AC distribution networks, which have been recently reported in the scientific literature. These power flow methods are (i) ...
LQR-Based adaptive virtual inertia for grid integration of wind energy conversion system based on synchronverter model
(2021-03-06)
This paper proposes adaptive virtual inertia for the synchronverter model implemented in a wind turbine generator system integrated into the grid through a back-to-back converter. A linear dynamic system is developed for ...
Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...
