RTC-method for the control of nuclear reactor power

Wajdi A. Ratemi (1998)

Kybernetika

Similarity:

In this paper, a new concept of the Reactivity Trace Curve (RTC) for reactor power control is presented. The concept is demonstrated for a reactor model with one group of delayed neutrons, where the reactivity trace curve is simply a closed form exponential solution of the RTC-differential equation identifier. An extended reactor model of multigroup (six groups) of delayed neutrons is discussed for power control using the RTC-method which is based on numerical solution of the governing...

Automatically Removing Widows and Orphans with lua-widow-control

Max Chernoff (2022)

Zpravodaj Československého sdružení uživatelů TeXu

Similarity:

The lua-widow-control package, for plain LuaTeX/LuaLaTeX/ConTeXt/OpTeX, removes widows and orphans without any user intervention. Using the power of LuaTeX, it does so without stretching any vertical glue or shortening any pages or columns. Instead, lua-widow-control automatically lengthens a paragraph on a page or column where a widow or orphan would otherwise occur. To use the lua-widow-control package, all that most LaTeX users need do is place in their preamble. No further changes...

Comparison of active control techniques over a dihedral plane

Emmanuel Creusé (2010)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

This work is devoted to the numerical comparison of four active control techniques in order to increase the pressure recovery generated by the deceleration of a slightly compressible viscous flow over a dihedral plane. It is performed by the use of vortex generator jets and intrusive sensors. The governing equations, the two-dimensional direct numerical simulation code and the flow configuration are first briefly recalled. Then, the objective of the control is carefully displayed,...

Dynamic coverage control design of multi-agent systems under ellipse sensing regions

Longbiao Ma, Fenghua He, Long Wang, Denggao Ji, Yu Yao (2018)

Kybernetika

Similarity:

This paper studies the dynamic coverage control problem for cooperative region reconnaissance where a group of agents are required to reconnoitre a given region. The main challenge of this problem is that the sensing region of each agent is an ellipse. This modeling results in asymmetric(directed) interactions among agents. First, the region reconnaissance is formulated as a coverage problem, where each point in the given region should be surveyed until a preset level is achieved. Then,...

A novel LMI-based robust model predictive control for DFIG-based wind energy conversion systems

Amir Gholami, Alireza Sahab, Abdolreza Tavakoli, Behnam Alizadeh (2019)

Kybernetika

Similarity:

The optimal and reliable performance of doubly fed induction generator is essential for the efficient and optimal operation of wind energy conversion systems. This paper considers the nonlinear dynamic of a DFIG linked to a power grid and presents a new robust model predictive control technique of active and reactive power by the use of the linear matrix inequality in DFIG-based WECS. The control law is obtained through the LMI-based model predictive control that allows considering both...
