Control de posición de un sistema hidráulico mediante un controlador por realimentación de estados

Abstract

This article shows the controller design for a hydraulic system, which consists of a servo-valve, a position sensor, a linear cylinder, a filter, and a hydraulic unit. Data samples are obtained from the real system input and output using a data acquisition board from National Instruments (usb-6211) and Matlab’s Data Acquisition Toolbox. These data are processed with the System Identification Toolbox of Matlab, to provide a suitable model that describes a similar behavior to the real hydraulic system, for which is designed a state feedback controller and root locus, that works to control the hydraulic system through the data acquisition board and a pc on real time.
