Получены формулы для представления решений линейных непрерывных $2\mathrm{D}$ систем, в том числе указана возможность расширения методов операционного исчисления путем построения соответствующих интегральных преобразований по пространственной переменной. Рассмотрены линейно-квадратичные задачи оптимизации, для которых получены соответствующие условия оптимальности и форма представления оптимального управления.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents an extension of discrete $2\mathrm{D}$ systems of Roesser and Fornasini–Marchesini types for the continuous case. Formulas for solution representation of linear continuous $2\mathrm{D}$ systems are obtained, including the possibility of expanding the methods of operational calculus by constructing corresponding integral transformations with respect to the spatial variable. Some linear-quadratic optimization problems are considered and the corresponding optimality conditions based on the operator setting are stated. Also, some form of the optimal control representation is presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многомерные $m$D системы</kwd><kwd>дискретные модели Россера и Форназини–Маркезини</kwd><kwd>обобщения линейных 2D систем на непрерывный случай</kwd><kwd>представление решений</kwd><kwd>операционное исчисление</kwd><kwd>линейно-квадратичные задачи оптимизации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multidimensional $m$D systems</kwd><kwd>Roesser and Fornasini–Marchesini discrete state-space models</kwd><kwd>Continuous versions of 2D systems</kwd><kwd>Operational calculus</kwd><kwd>Optimization problems</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bose N.
