Diseño del Control de Caudal y Presión de una Válvula de Flujo Anular para el Llenado de Tanques de Agua Potable

Abstract

The purpose of this work was to develop the modeling and control of an annular flow valve that contributes to the filling of tank flow for the water supply station in the Codito 2 neighborhood in the city of Bogotá. In this project, the operation of the annular flow valve was designed, model and verified with the aim of designing different control models that would allow to improve the performance of the valve, specifically the opening percentage in relation to the flow reaching it. This work observed the effect of water flows between 13 L / s and 78 L / s (verified from the station sensors), during a normal working hour. Likewise, the valve opening percentage was analyzed and recorded for the range of flows mentioned above, obtaining results that indicated a proportional behavior in the valve, with which the operation of a proportional, integral, and derivative controller was subsequently designed and verified (PID), a controller based on lag and lead compensation, and finally one based on state spaces. For the case of this report, it will focus more on the development, analysis, and comparison of each of the types of controllers than on the system model. Although, the necessary equations were also analyzed and developed to be able to be modeled in the program, which led to a simulation using the tool that integrates the program; simulink, with which it was possible to verify the operation of each controller visually.
