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 ...More
In this paper we investigate the problem of distributed optimal control for the oscillation processes described by Fredholm integro-differential equations with partial derivatives when the function of the external source depends nonlinearly on the control parameters. We have developed an algorithm for finding approximate solutions of nonlinear optimization problems with arbitrary precision. The developed method of solving nonlinear optimization problems is constructive and can be used in applications. -
