A system for the control of the pressure difference at the LAV testing line in Danfoss Trata

Customer

Danfoss Trata, Ljubljana

Duration

2003

Objectives

Design and implementation of a control system to control the line for testing and assessment of various types of control valves used in district-heating systems.

Description

The control of the pressure difference on the valve under test by adjusting the speed of the pumps.

Innovation

Model-based self-tuning control of the pressure difference, taking into account the nonlinearity of the valve characteristics, which varies with different types of valves.

Benefits

Simple, fully autonomous testing of different types of valves under
