On the Solvability of a Nonlinear Tracking Problem Under Boundary Control for the Elastic Oscillations Described by Fredholm Integro-Differential Equations

Elmira ABDILDAYEVA

In the present paper we investigate nonlinear tracking problem under boundary control for the oscillation processes described by Fredholm integro-differential equations. When we investigate this problem we use notion of a weak generalized solution of the boundary value problem. Based on the maximum principle for distributed systems we obtain optimality conditions from which follow the nonlinear integral equation of optimal control and the differential inequality.We have developed an algorithm to construct the optimization problem solution. This solving method of a nonlinear tracking problem is ...Более

On the property of equal ratios in the problem of boundary vector control of elastic vibrations described by Fredholm integro-differential equations = О равных отношениях в задаче граничного векторного управления упругими колебаниями, описываемыми фредгольмовыми интегро-дифференциальными уравнениями

Elmira ABDILDAYEVA

В статье исследуется нелинейная задача оптимального управления упругими колебаниями, описываемыми фредгольмовыми интегро-дифференциальными уравнениями в случае, когда управление осуществляется граничными источниками. В исследовании использовано понятие обобщенного решения краевой задачи управляемого процесса. На основе принципа максимума для систем с распределенными параметрами получены условия оптимальности в виде систем равенств и неравенств. Обнаружено, что условия оптимальности в виде равенств обладают свойством равных отношений. Это обстоятельство позволило упростить процедуру построения ...Более

On the Solvability of a Nonlinear Optimization Problem for Thermal Processes Described by Fredholm Integro-Differential Equations with External and Boundary Controls

Elmira ABDILDAYEVA

In the present paper we studied the problem of nonlinear optimal control of the thermal processes described by Fredholm integro-differential equations when the control parameters are nonlinearly included into the equation as well as into the boundary condition. The concept of weak generalized solution of the boundary value problem is introduced and the algorithm for its construction is indicated. It is established that optimal control is defined as the solution of the system of nonlinear integral equations which contain unknown functions under and out of the integral and satisfy the additional ...Более

Method of spherical harmonic series in the problem of minimization of atmosphere pollution by fractions of harmful admixtures

Ramiz RAFATOV

The problem of minimization of atmosphere pollution by fractions of harmful admixtures is studied. It is supposed that a controlled object is described by non-stationary integral–differential transfer equation with special boundary conditions and control parameters, which are included in the right part of equation as delta-functions. Minimized integral quadratic functional characterizes energy expenditure for control and depends on the average squared deflection of fraction concentration from the desired final state. Optimal conditions are obtained with the help of Pontryagin’s maximum princip ...Более

On the Solvability of Tracking Problem with Nonlinearly Distributed Control for the Oscillation Process

Elmira ABDILDAYEVA

In the paper we investigate the unique solvability of the tracking problem with the distributed optimal control for the elastic oscillations described by Fredholm integro-differential equations. The sufficient conditions are found for existence of a unique solution to the boundary value problem, also the class of functions of external influence for which the optimization problem has a solution. The algorithm was developed for constructing the complete solution of the tracking problem of nonlinear optimization.
