Show all documents Numerical solution of systems of linear Volterra integral equations using block-pulse functions Block - Pulse functions have been used by many researchers for various problems such as solving differential equations [12], integral equations [6], population balance equations [5]. Babolian presented a direct method to solve Volterra integral equation of the first kind using operational matrix with BPFs [2].

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. Convergence analysis of this method is discussed. Finally an illustrative example is given to show the accuracy of the proposed method so the results of it is compared with the block-pulse functions BPFs method.

Block-Pulse Function

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.

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.

This paper deals with an optimal control problem with quadratic cost for a class of bilinear systems using the orthogonal functions technique. The main idea of this technique is that it reduces the problem to solving a system of algebraic equations, thus simplifying the problem. The control variable and the state variables are approximated by block pulse functions series. Then the system dynamics is transformed into systems of algebraic equations. Finally, numerical results are given to illustrate the proposed method.

Block Pulse Functions and Their Applications in Control Systems

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.

Supervisory control and data acquisition SCADA is a control system architecture comprising computers , networked data communications and graphical user interfaces GUI for high-level process supervisory management, while also comprising other peripheral devices like programmable logic controllers PLC and discrete proportional-integral-derivative PID controllers to interface with process plant or machinery. The use of SCADA has been considered also for management and operations of project-driven-process in construction. The operator interfaces which enable monitoring and the issuing of process commands, like controller set point changes, are handled through the SCADA computer system. The subordinated operations, e. The SCADA concept was developed to be a universal means of remote-access to a variety of local control modules, which could be from different manufacturers and allowing access through standard automation protocols.

Khajehnasiri Published The operational block-pulse functions, a well-known method for solving functional equations, is employed to solve a system of nonlinear Volterra integro-differential equations. First, we present the block-pulse operational matrix of integration, then by using these matrices, the nonlinear Volterra high-order integro-differential equation is reduced to an algebraic system.

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.

Стратмор потерпел неудачу. Я знаю, что ты о нем думаешь. - Это не имеет никакого отношения к Попрыгунчику, - резко парировала. Вот это чистая правда, - подумал Джабба. - Послушай, Мидж, к Стратмору я не отношусь ни плохо ни хорошо. Ну, понимаешь, он криптограф.

Повсюду в старинных домах отворялись ворота, и люди целыми семьями выходили на улицы. Подобно крови, бегущей по жилам старого квартала Санта-Крус, они устремлялись к сердцу народа, его истории, к своему Богу, своему собору и алтарю. Где-то в уголке сознания Беккера звонили колокола. Я не умер. Он с трудом открыл глаза и увидел первые солнечные лучи. Беккер прекрасно помнил все, что произошло, и опустил глаза, думая увидеть перед собой своего убийцу.

Тишина. Наверное, Меган, подумал. У нее оставалось целых пять часов до рейса, и она сказала, что попытается отмыть руку. - Меган? - позвал он и постучал. Никто не ответил, и Беккер толкнул дверь.

 Роса? - Беккер сжал руку Клушара. Старик застонал. - Он называл ее… - Речь его стала невнятной и едва слышной. Медсестра была уже совсем близко и что-то кричала Беккеру по-испански, но он ничего не слышал. Его глаза не отрывались от губ Клушара.

 - Я думаю, я поняла, что вам от меня.  - Она наклонилась и принялась рыться в сумке. Беккер был на седьмом небе. Кольцо у нее, сказал он. Наконец-то. Он не знал, каким образом она поняла, что ему нужно кольцо, но был слишком уставшим, чтобы терзаться этим вопросом.

С того момента как полицейский доставил сюда канадца, прошло уже несколько часов. Перелом запястья, разбитая голова - скорее всего ему оказали помощь и давно выписали. Беккер все же надеялся, что в клинике осталась какая-то регистрационная запись - название гостиницы, где остановился пациент, номер телефона, по которому его можно найти. Если повезет, он разыщет канадца, получит кольцо и тут же вернется домой. Если потребуется, заплатите за это кольцо хоть десять тысяч долларов.

Вот Танкадо вышел на открытое место и залюбовался открывшимся перед ним зрелищем. Он козырьком поднес руку к глазам и стал разглядывать шпили над внушительным фасадом. - Смотрите внимательно, - предупредил Смит.  - Халохот - профессионал. Это его первый выстрел в публичном месте.
