This paper deals with an optimal control problem with quadratic cost for a class of bilinear systems using the orthogonal functions technique.

This paper applied the idea of block pulse BP transform in the equivalent linearization of a nonlinear system. The BP transform gives effective tools to approximate complex problems. The main goal of this work is on using BP transform properties in process of linearization. The accuracy of the proposed method compared with the other equivalent linearization including the stochastic equivalent linearization and the regulation linearization methods.

## Block Pulse Functions and Their Applications in Control Systems

The present study tackles the tracking control problem for unstructured uncertain bilinear systems with multiple time-delayed states subject to control input constraints. First, a new method is introduced to design memory state feedback controllers with compensator gain based on the use of operational properties of block-pulse functions basis. The proposed technique permits transformation of the posed control problem into a constrained and robust optimization problem. The constrained robust least squares approach is then used for determination of the control gains. Second, new sufficient conditions are proposed for the practical stability analysis of the closed-loop system, where a domain of attraction is estimated. A real-world example, the headbox control of a paper machine, demonstrates the efficiency of the proposed method. Many physical systems existing in real life exhibit nonlinear behavior.

This method initially uses the solution of the direct method to obtain the more accurate solution. The convergence and error analysis of this method are given. Finally, numerical examples illustrate efficiency and accuracy of the proposed method. Also, the numerical results of this method are compared with the results of direct method, collocation method and iterated collocation method.

## Block-Pulse Function

Metrics details. In this paper, the block pulse function method is proposed for solving high-order differential equations associated with multi-point boundary conditions. Although the orthogonal block pulse functions frequently have been applied to approximate the solution of ordinary differential equations associated with the initial conditions, the presented method provides the flexibility with respect to multi-point boundary conditions in separated or non-separated forms. This technique, which may be named the augmented block pulse function method, reduces a system of high-order boundary value problems of ordinary differential equations to a system of algebraic equations. The illustrated results confirm the computational efficiency, reliability, and simplicity of the presented method. The systems of ordinary differential equations ODEs with different boundary conditions are well known for their applications in biology, chemistry, physics, engineering, and sciences [ 1 — 4 ]. There are many different reliable methods which can find the solution of ODEs for simple forms of boundary conditions.

Присоединяются зарубежные налетчики! - крикнул один из техников.  - Уже обо всем пронюхали. Сьюзан отвернулась от экрана ВР к боковому монитору.

Анализ затрат на единицу продукции.  - Мидж торопливо пересказала все, что они обнаружили с Бринкерхоффом. - Вы звонили Стратмору.

Он отличался громким голосом и безвкусно-крикливой манерой одеваться. Коллеги-криптографы прозвали его Галит - таково научное название каменной соли. Хейл же был уверен, что галит - некий драгоценный камень, поэтому считал, что это прозвище вполне соответствует его выдающимся умственным способностям и прекрасному телосложению.

Абсолютно .

Да… и… - слова застревали у нее в горле. Он убил Дэвида. Бринкерхофф положил руку ей на плечо. - Мы почти приехали, мисс Флетчер. Держитесь.

Черный лед. В центре помещения из пола торчала, подобно носу исполинской торпеды, верхняя часть машины, ради которой было возведено все здание. Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол. Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море.

Сигналы продолжались. Источник их находился где-то совсем близко. Сьюзан поворачивалась то влево, то вправо.

Если все сложится нормально, она скоро выяснит местонахождение Северной Дакоты, и Стратмор конфискует ключ. Тогда дело будет только за Дэвидом. Когда он найдет копию ключа, имевшуюся у Танкадо, оба экземпляра будут уничтожены, а маленькая бомба с часовым механизмом, заложенная Танкадо, - обезврежена и превратится во взрывное устройство без детонатора.

- Я только что говорила с Джаббой. Он сказал, что в прошлом году сам установил переключатель. Личный помощник директора отказывался верить ее словам.

In this paper, two-dimensional modified block-pulse functions 2D-MBPFs method is introduced for approximate solution of 2D-linear stochastic Volterra-Fredholm integral equations so the ordinary and stochastic operrational matrices of integration are utilized to reduce the computation of such equations into some algebraic equations.
