Robust adaptive control using multiple models, switching and tuning
(Inst Engineering Technology-iet, 2011-12)
The supervisory control problem is analysed as an online robust design problem using switching to select the relevant models for designing the control law. The proposed supervisory control algorithm is based on the integration ...
Power conditioning system coupled with a flow battery for wind energy applications: Modelling and control design
(Institution of Engineering and Technology, 2017-06)
Wind generation (WG) is the most widespread renewable energy resource in the world. However, this implementation inevitably leads to an increase in the problems caused by WG, e.g. frequency oscillations, power fluctuations ...
Tracking Control Design in Nonlinear Multivariable Systems: Robotic Applications
(Hindawi Publishing Corporation, 2019-08)
In this work, a controller design technique called linear algebra based controller (LABC) is presented. The controller is obtained following a systematic procedure that is summarized in this work. In addition, the influence ...
Korobov's controllability function method applied to finite-time stabilization of the Rössler system via bounded controls
(Karazin Kharkiv National University, 2020-06)
The problem of stabilizing the Rossler system in nite time by bounded controlis considered. We employ V. I. Korobov's controllability function method, whichinvolves a Lyapunov-type function. The controllability function ...
Multiple resonant controllers strategy to achieve fault ride-through and high performance output voltage in UPS applications
(The Institution of Engineering and Technology, 2018-11-13)
A control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy ...
Thyristor-based flexible ac transmission system for controlling the vanadium redox flow battery
(Inst Engineering Technology-iet, 2013-05)
The vanadium redox flow battery (VRB) is a large stationary energy storage system; which presents high-speed response and overload capacity characteristics. The VRB produces a dc voltage between two terminals; so a power ...
Non-zero set-point affine feedback control of impulsive systems with application to biomedical processes
(Taylor & Francis Ltd, 2018-11)
Linear impulsive systems have been extensively studied in the last decades, mainly in the field of biomedical research. However, a proper characterisation of the equilibria of such a systems - when they are out of the ...
Evaluation of the design effects of different agropastoral systems on the diversity and density of spiders
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2017)
Sustainable agro-ecological design is challenging when the goal is self-regulation of the system. The objective of this study was to evaluate if the agropastoral design system affects the spider community, as spiders are ...
Stabilisation of grid assistance for a renewable hydrogen generation system by min-projection strategy
(Institution of Engineering and Technology, 2016-01)
Control of grid assistance is proposed in this study for a renewable hydrogen generation system of simple and robust structure. Here, the grid connection serves the dual purpose of minimising the effect of wind power ...
Time-optimal control fields for quantum systems with multiple avoided crossings
(American Physical Society, 2015-10)
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optimal ...
