Многопараметрический пневмомеханический датчик позиционных пневмоприводов

Многопараметрический пневмомеханический датчик позиционных пневмоприводов

Abstract

В статье рассматривается автоматизированный позиционный привод технологических систем повышенного быстродействия и точности на основе многопараметрического пневмомеханического датчика (МПМД). Предлагается схемо-техническое решение (МПМД) с улучшенными интегральными оценками нескольких параметров позиционных перемещений объектов управления. Разработана обобщённая математическая модель датчика в структуре позиционного пневмопривода. Вычислительным экспериментом методом Рунге-Кутта в среде пакета программы Мatlab-simulink получены зависимости основных параметров позиционного пневмопривода. При выполнении типового позиционного цикла установлено влияние основных геометрических, гидравлических, термодинамических характеристик процесса истечения сжатого воздуха через сопловой элемент датчика на его расходно-перепадную характеристику. Установлено, что максимальное отклонение не превышает 5% от эталонного датчика. Это позволило повысить точность параметрической оценки процесса позиционирования и формирования управляющих воздействий в реальном пространстве и времени.

In the article the automatic drive positioner technology systems increased speed and accuracy on the basis of multi-parameter sensor rotor (MPMD). The proposed scheme, technical solution (MPMD) with improved integral evaluation of several parameters of positional displacement control objects. The generalized mathematical model of the sensor actuator position struktre. Computational experiments by the Runge-Kutta in the environment of the program Matlab-simulink are obtained depending on the basic parameters of an actuator position. When you perform a typical positional cycle The influence of the major geometric, hydraulic and thermodynamic characteristics of the expiry of the compressed air through the nozzle sensor element on its expenditure-Perepadnaya response. It is found that the maximum deviation does not exceed 5% of the reference sensor. This will improve the accuracy of parameter estimation process of positioning and formation of control actions in real space and time.
