These sets are considered gray areas rather than black and white in contrast to classical sets which form the basis of binary or Boolean logic.

Fuzzy control system

The use of fuzzy set theory in the social sciences is certainly not widespread, but ever since the early pioneering proposals see e. Nowadays, one can find several noteworthy examples in the field of social simulation and related domains Denize et al. Power and Neumann et al. There is also a NetLogo Wilensky extension developed to facilitate the implementation of fuzzy approaches in agent-based simulations Izquierdo et al. This widespread availability of ready-to-use software, the willingness of a community eager to apply new tools to the analysis of complex systems, and the apparent simplicity of the basic principles of fuzzy logic have led to a situation in which any scholar can nowadays build and use a simple fuzzy logic model in a matter of hours. This paper focuses on the use of Mamdani inference, which is one of the most popular techniques in applied fuzzy logic. Mamdani inference is mainly used in fuzzy control Driankov et al.

Control of electrical drives based on fuzzy logic

In general, the modelling of wind turbines is a challenging task, since they are complex dynamic systems, whose aerodynamics are nonlinear and unsteady. Accurate models should contain many degrees of freedom, and their control algorithm design must account for these complexities. However, these algorithms must capture the most important turbine dynamics without being too complex and unwieldy, mainly when they have to be implemented in real-time applications. The first contribution of this work consists of providing an application example of the design and testing through simulations, of a data-driven fuzzy wind turbine control. In particular, the strategy is based on fuzzy modelling and identification approaches to model-based control design. Fuzzy modelling and identification can represent an alternative for developing experimental models of complex systems, directly derived directly from measured input-output data without detailed system assumptions.

A fuzzy control system is a control system based on fuzzy logic —a mathematical system that analyzes analog input values in terms of logical variables that take on continuous values between 0 and 1, in contrast to classical or digital logic, which operates on discrete values of either 1 or 0 true or false, respectively. Fuzzy logic is widely used in machine control. The term "fuzzy" refers to the fact that the logic involved can deal with concepts that cannot be expressed as the "true" or "false" but rather as "partially true". Although alternative approaches such as genetic algorithms and neural networks can perform just as well as fuzzy logic in many cases, fuzzy logic has the advantage that the solution to the problem can be cast in terms that human operators can understand, so that their experience can be used in the design of the controller. This makes it easier to mechanize tasks that are already successfully performed by humans. Fuzzy logic was proposed by Lotfi A. Zadeh of the University of California at Berkeley in a paper.

Application of a Data-Driven Fuzzy Control Design to a Wind Turbine Benchmark Model

The paper presents the theory of control systems for electrical drives based on fuzzy logic, from the author's point of view. The paper offers practical answers at questions related to the design of speed control systems based on fuzzy PI speed controller: what is the adequate structure of fuzzy controller, the number of rules fuzzy values, how to assure stability, implementation, control system quality criteria.

The arithmetic of PID control is simple and the stability of it is good. However, the dynamic characteristics of PID control are poor [3]. The fuzzy logic control method is flexible and adaptive and does not rely on a mathematical model of the system and can deal with the nonlinearity of parameters and uncertain problems [1].

Design, Simulation and Implementation of a Fuzzy-PID Controller for Controlling a DC-DC Converter

Сьюзан отвечала на те вопросы, на которые могла ответить, и постепенно у Дэвида сложилось общее представление об Агентстве национальной безопасности - за исключением, разумеется, секретных сторон деятельности этого учреждения. Основанное президентом Трумэном в 12 часов 01 минуту 4 ноября 1952 года, АНБ на протяжении почти пятидесяти лет оставалось самым засекреченным разведывательным ведомством во всем мире. Семистраничная доктрина сжато излагала программу его работы: защищать системы связи американского правительства и перехватывать сообщения зарубежных государств. На крыше главного служебного здания АНБ вырос лес из более чем пятисот антенн, среди которых были две большие антенны, закрытые обтекателями, похожими на громадные мячи для гольфа. Само здание также было гигантских размеров - его площадь составляла более двух миллионов квадратных футов, вдвое больше площади штаб-квартиры ЦРУ. Внутри было протянуто восемь миллионов футов телефонного кабеля, общая площадь постоянно закрытых окон составляла восемьдесят тысяч квадратных футов. Сьюзан рассказала Дэвиду про КОМИ НТ, подразделение глобальной разведки, в распоряжении которого находилось немыслимое количество постов прослушивания, спутников-шпионов и подслушивающих устройств по всему земному шару.
