Методы решения граничных задач теории управления
В монографии представлены разработанные алгоритмы построения различных типов управляющих функций, обеспечивающие перевод широкого класса линейных и нелинейных систем обыкновенных дифференциальных уравнений на конечном и бесконечном промежутках времени с учетом ограниченности, дискретности, запаздывания управляющего сигнала, неполной информации о фазовом состоянии объекта, а также заранее неизвестных возмущений. Найдены достаточно легко проверяемые условия, гарантирующие реализацию полученных алгоритмов. Эффективность методов иллюстрируется на решении конкретных практических задач и их численном моделировании. Монография адресована научным работникам, специализирующимся в области математической теории управления, может быть полезна и студентам старших курсов математических специальностей.
