A data acquisition system using LabVIEW software and the Arduino microcontroller for a test bench of centrifugal pumps connected in series and parallel has been developed. The acquisition system allows real-time display of centrifugal pump discharge pressure values, voltage, current and volumetric flow of the test bench. A description of the system operation (front panel and block diagram) as well as the elements (actuators, instruments, controller and software) used in the system is given. From the front panel it became possible to operate the test bench for three modes of operation (Individual, Series and Parallel). Pressure, voltage, current and volumetric flow values were recorded over time and stored in a text file generated by the acquisition system.

Este documento describe el modelamiento de un convertidor AC-DC y el diseño de una técnica de Control Proporcional Integral Generalizado (GPI). El diseño de dicha técnica se da en el contexto del rechazo activo de perturbaciones (ADRC), en el cual se muestra que las técnicas de control GPI son capaces de rechazar las perturbaciones de carácter endógeno y exógeno de la planta,  lo que lleva a un error de seguimiento acotado y dicha cota puede hacerse tan pequeña como se quiera al alejar las raíces del eje imaginario.
