Система адаптивного управления и диагностики сервомоторов направляющего аппарата гидроагрегата с поворотно-лопастной турбиной

Abstract

The article is concerned with problems of modern electrohydraulic converters control systems used to adjust wicket gate of Kaplan turbine. Linearized model of wicket gate servomotor is considered. Algorithm for online identification of parameters of servomotor is considered. Algorithm is based on recurrent least squares method. Algorithm for adaptive PI-regulator tunning is based on online optimization of functional of generalised work (FGW). Model experiments using real data show reducing maximum control error of servomotor position from 20 % to 1 %. Also methods for servomotor state diagnostic are considered.

Рассматривается синтез системы адаптивного управления и диагностики сервомоторов направляющего аппарата гидроагрегата с поворотно-лопастной турбиной. Приведены критерии качества обучения моделей и критерий качества управления в виде квадратичного функционала обобщенной работы. Рассмотрены основные методы диагностирования сервомоторов.
