Discrete fractional - order control system

Nikolov, Emil Kostov; Николов, Емил Костов, (2004)
In the present article are proposed: structure of a fractional order control system; method for the synthesis of a fractional algorithm of a new class; method for a discretization of the fractional algorithm; it is deducated a finite difference equation suitable for a direct configuration of discrete controllers; it is submitted and solved ...
Мярка за нелинейност в системите за управление

Перев, Камен Лазаров; Perev, Kamen Lazarov, (2004)
This paper considers the notion of nonlinearity measure in control systems. The nonlinearity measure determines the distance between a given nonlinear system and its local linearization for particular set of input signals. One of the most important applications of the noniinearity measure is in determining the linearizing effect of feedback ...
Устойчивост на затворени линейни системи за управление с интервални данни

Колев, Любомир Варадинов; Филипова-Петракиева, Симона Кирилова; Kolev, Lyubomir Varadinov; Filipova-Petrakieva, Sinoma Kirilova, (2004)
In this paper the problem of stability analysis of linear closed-looped systems under interval uncertainties is considered. The problem is reduced to the problem of determining outer bounds on the ranges of the eigenvalues of interval matrices with dependent coefficients with respect to the independent elements of all other interval matrices ...
Сравнителен анализ на някои алгоритми за синтез на линейни стохастични адаптивни системи за управление

Маджаров, Никола Енчев; Славов, Цоньо Николаев; Madzharov, Nikola Enchev; Slavov, Tsonyo Nikolaev, (2004)
A comparative analysis of some algorithms for design of linear stochastic systems with indirect adaptation is described in this paper. The comparing systems realized on basis of some estimation algorithms — recursive least-square algorithm, recursive least-square algorithm with multiple Kalman filter and recursive lest-square algorithm with ...
Синтез на слабо нелинейни автоколебателни системи

Савов, Весел Николаев; Георгиев, Живко Димитров; Тодоров, Тодор Георгиев; Savov, Vesel Nikolaev; Georgiev, Zgivko Dimitrov; Todorov, Todor Georgiev, (2004)
A method for the synthesis of weakly nonlinear oscillators systems by using qualitative theory of differential equations analysis is proposed in this article. The self- sustained oscillations in such systems are regarded as limit cycles. The synthesis of weakly nonlinear oscillators systems possessing limit cycles with preliminarily assigned ...
