Показано, что расчетное значение перепада давления и расхода во всем диапазоне рабочих нагрузок и скоростей вращения ротора насоса отличается от измеренного не более чем на 10%. Демонстрируется возможность включения созданных средств в систему управления осевым насосом крови для протезирования функций левого желудочка сердца. </p></abstract><trans-abstract xml:lang="en"><p>The article describes complex software to calculate the main parameters of the axial pump (pressure drop and flow rate) on the basis of an analysis of its technical characteristics (current consumption and pump speed). It is shown that the calculated value of pressure drop and flow rate throughout the range of operating loads and pump speeds is different from the measured one by no more than 10%. It is shown that this software package may be included in the control system of axial pump. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>роторные насосы</kwd><kwd>скорость вращения ротора</kwd><kwd>расход насоса</kwd><kwd>напор насоса</kwd><kwd>алгоритм управления</kwd><kwd>косвенные измерения</kwd><kwd>потребляемый ток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rotary pump</kwd><kwd>pump speed</kwd><kwd>flow rate</kwd><kwd>pressure drop</kwd><kwd>control system</kwd><kwd>noninvasive monitoring</kwd><kwd>current consumption</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">Stevenson LW, Kormos RL.
