Sliding mode control law for a variable speedwind turbine
(WSEAS, 2011)
Modern wind turbines are designed in order to work in variable speed operations. To perform this task, wind turbines are provided with adjustable speed generators, like the double feed induction generator. One of the main ...
Generalized Predictive Control Scheme for a Wind Turbine System
(MDPI, 2022)
In this paper, a generalized predictive control scheme for wind energy conversion systems that consists of a wind turbine and a doubly-fed induction generator is proposed. The design is created by using the maximum power ...
Design and experimental validation of a piezoelectric actuator tracking control based on fuzzy logic and neural compensation
(Elsevier, 2023-07)
This work proposes two control feedback-feedforward algorithms, based on fuzzy logic in combination with neural networks, aimed at reducing the tracking error and improving the actuation signal of piezoelectric actuators. ...
Magnetic Design of a 3-Phase SiC-Based PV Inverter With DC-Link Referenced Output Filter
(IEEE, 2023-04)
The use of Silicon carbide (SiC) devices represents an improvement in terms of size, weight and efficiency of power converters. However, SiC-based solutions present high dv/dt and di/dt on the switching events, increasing ...
An improved predictive current control for IM drives
(Elsevier, 2023-08)
In Finite Control Set-Model Predictive Control (FCS-MPC), the model of the induction machine (IM) is
expressed in the a b or d q reference frame, and then the back-EMF is estimated based on the applied
voltage vectors. ...
PEMFC Current Control Using a Novel Compound Controller Enhanced by the Black Widow Algorithm: A Comprehensive Simulation Study
(MDPI, 2023-09-16)
Proton exchange membrane fuel cells (PEMFCs) play a crucial role in clean energy systems. Effective control of these systems is essential to optimize their performance. However, conventional control methods exhibit limitations ...
Low Effort L-i Nuclear Fusion Plasma Control Using Model Predictive Control Laws
(Hindawi Publishing, 2015)
One of the main problems of fusion energy is to achieve longer pulse duration by avoiding the premature reaction decay due to plasma instabilities. The control of the plasma inductance arises as an essential tool for the ...
Suboptimal regulation of a class of bilinear interconnected systems with finite-time sliding planning horizons
(Hindawi Publishing Corporation, 2008)
This paper focuses on the suboptimization of a class of multivariable discrete-time bilinear systems consisting of interconnected bilinear subsystems with respect to a linear quadratic optimal regulation criterion which ...
Pitch Control of Wind Turbine Blades Using Fractional Particle Swarm Optimization
(MDPI, 2022-12-26)
To achieve the maximum power from wind in variable-speed regions of wind turbines (WTs), a suitable control signal should be applied to the pitch angle of the blades. However, the available uncertainty in the modeling of ...
Experimental validation of fuzzy type-2 against type-1 scheme applied in DC/DC converter integrated to a PEM fuel cell system
(Wiley, 2023-02)
This research presents and compares the outcomes of experimental implementations of different fuzzy logic control structures for a proton exchange membrane fuel cell (PEMFC). These devices are well known for their capability ...
