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