Adaptive tracking electro-hydraulic drive

Адаптивный следящий электрогидравлический привод

Adaptive tracking electro-hydraulic drive

Abstract

Статья посвящена исследованию возможностей снижения влияния параметрических возмущений на показатели назначения корабельного артиллерийского комплекса. Предложен закон адаптивного управления слежением в аналитической форме и способ его технической реализации для снижения чувствительности следящего электрогидравлического привода артиллерийского комплекса к параметрическим возмущениям, возникающим в процессе эксплуатации и приводящих к нежелательным колебаниям объекта управления (вооружения), снижающих показатели его точности. В основе предложенного закона адаптивного лежит локальная оптимизация ошибки слежения (рассогласования) по квадратичному критерию относительно эталонного процесса с заданными свойствами. Структура регулятора, реализующая такой закон адаптивного управления, совпадает со структурой традиционного ПИД регулятора, что прямо указывает на способ его технической реализации. Введение адаптивного регулятора в контур следящего электрогидравлического привода-прототипа снижает его чувствительность к параметрическим возмущениям. При этом первоначальная структура привода существенно не меняется и не требуются дополнительные регулировки. Об этом свидетельствуют результаты компьютерного моделирования, выполненного в среде MATLAB & Simulink. The article is devoted to the study of the possibilities of reducing the influence of parametric disturbances on the indicators of the purpose of the ship's artillery complex. A law of adaptive tracking control in analytical form and a method for its technical implementation are proposed to reduce the sensitivity of the tracking electro-hydraulic drive of an artillery complex to parametric disturbances arising during operation and leading to unwanted oscillations of the control object (weapon), which reduce its accuracy. The proposed adaptive law is based on the local optimization of the tracking error (mismatch) by the quadratic criterion relative to the reference process with the given properties. The structure of the controller that implements such a law of adaptive control coincides with the structure of a traditional PID controller, which directly indicates the way of its technical implementation. The introduction of an adaptive controller into the prototype tracking electro-hydraulic drive circuit reduces its sensitivity to parametric disturbances. At the same time, the initial structure of the drive does not change significantly and additional adjustments are not required. This is evidenced by the results of computer simulations performed in MATLAB & Simulink.
