New options in comparing controllers for hydraulic plants using Matlab tool

Abstract

This paper describes new options added to Matlab/Simulink tool for computer support of the controller design for hydraulic plants. This recently published application can run locally, or through the Internet as a virtual laboratory. The newly developed options extend the disturbance observer based one-tank control by a disturbance feedforward requiring introduction of disturbance reference model. Evaluation of the noise impact is enabled using data sets for calculation of performance measures allowing separate quantification of beneficial and useless signal changes at the plant input and output.
