В ходе этих операций в мозг через отверстие в черепе вводится специальная игла. Эта игла перемещается в ткани мозга таким образом, чтобы ее кончик достиг определенной точки, после чего выполняется необходимая медицинская манипуляция (например, взятие пункции). Для обеспечения точности позиционирования иглы целесообразно контролировать ход операции с помощью аппарата магнитно-резонансной томографии. Это накладывает ограничения на тип приводов, которые можно использовать для управления иглой. В работе рассмотрена задача об управлении внедрением иглы цилиндрической формы в фантом головного мозга, причем управляющая сила формируется с помощью пьезоэлектрического привода (ПЭП). Для описания взаимодействия иглы с тканью предложена феноменологическая модель, в рамках которой предполагается, что ткань фантома представляет собой вязкоупругий и пластический материал, а также обладает релаксационными свойствами. При описании сил, действующих на боковую поверхность иглы со стороны ткани, учитывается наличие сухого трения. Предложенная модель содержит ряд параметров, которые идентифицируются на основе экспериментов, проведенных в Национальном университете Cheng Kung (Тайвань). В ходе этих экспериментов стандартная игла для биопсии внедрялась в фантом, изготовленный из раствора агар-агара, причем регистрировались положение иглы и сила, действующая на нее со стороны ткани. Показано, что результаты экспериментов достаточно хорошо согласуются с расчетами в рамках модели. Предложен алгоритм управления иглой путем задания частоты возбуждения ПЭП. Целью управления является внедрение иглы на заданную глубину с заданной постоянной скоростью с последующим удержанием иглы на этой глубине. При этом требуется избежать перерегулирования по скорости и положению. Проведено численное моделирование. Исследовано влияние параметров обратной связи на характер процесса. Показано, что при надлежащем выборе параметров удается избежать перерегулирования.</p></abstract><trans-abstract xml:lang="en"><p>Currently, stereotaxic brain surgery is an actively developing branch of medicine. During these operations, a special needle is inserted into the brain through a hole in the skull. This needle is moved in the brain tissue so that its tip reaches a certain point, after which the necessary medical manipulation is performed (for example, taking a puncture). To ensure accurate positioning of the needle, it is advisable to monitor the process of such operations using the magnetic resonance imaging apparatus. This puts restrictions on the type of actuators that can be used to drive the needle. The paper considers the problem of controlling the penetration of a cylindrical needle into a phantom of the brain where the control force is generated using a piezoelectric drive (PED). To describe the interaction of the needle with the tissue, a phenomenological model is proposed, under which it is assumed that the phantom tissue is a viscoelastic and plastic material, and also demonstrates relaxation properties. When describing forces acting on the lateral surface of the needle from the side of the tissue, the presence of dry friction is taken into account. The proposed model contains a number of parameters that are identified based on experiments carried out at the NCKU (Taiwan). In these experiments, a standard biopsy needle was inserted into a phantom made from agar-agar solution, and the position of the needle and the force acting on it from the tissue were registered. It is shown that the experimental results are in good agreement with the calculations in the context of the model. An algorithm for controlling the needle by setting the frequency of excitation of the probe is proposed. The aim of the control is to introduce the needle to a given depth at a given constant speed, and then hold the needle at this depth. During the process, it is required to avoid overshooting in speed and position. Numerical simulation has been carried out. The effect of the feedback parameters on the nature of the process is investigated. It is shown that the proper choice of parameters allows for avoiding the overshooting.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стереотаксическая операция</kwd><kwd>пьезоэлектрический привод</kwd><kwd>математическая модель</kwd><kwd>контактные характеристики</kwd><kwd>алгоритм управления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stereotactic operation</kwd><kwd>piezoelectric drive</kwd><kwd>mathematical model</kwd><kwd>contact characteristics</kwd><kwd>control algorithm</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке РФФИ (проект 19-58-52004) и министерства науки и технологий Тайваня (MOST 108-2923-E-006-003-MY3).</funding-statement><funding-statement xml:lang="en">The work is partially supported by RFBR (Project No. 19-58-52004) and the Ministry of Science and Technology of Taiwan (project MOST 108-2923-E-006-003-MY3).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Poole E.
