Para llevar a cabo el modelado matemático de la tubería, se emplean las ecuaciones de Golpe de Ariete, las cuales son discretizadas utilizando el Método de Colocación. Posteriormente, se aborda la tarea de Detección y Localización de obstrucciones, donde se implementa un observador del tipo Kalman Extendido. Este observador tiene la capacidad de estimar simultáneamente la posición en la tubería (𝒛𝒄) donde se está presentando la obstrucción y el porcentaje de área de obstrucción (𝑨𝒐). El observador presenta un buen desempeño y es sometido a diversas pruebas, incluyendo su utilización en un modelo de tubería discretizado mediante el Método de
This paper presents the mathematical modeling of a pipeline system that will be used in the detection and location blockages with state observers. The pipeline mathematical modeling is carried out with the Water Hammer Equations, which are discretized using the Collocation Method. Subsequently, the detection and location blockage tasks are addressed, where an extended Kalman observer is implemented. This observer has the ability to simultaneously estimate the pipe position (zc) where blockage is occurring and the blockage area percentage (Ao). The observer presents a good performance and is subjected to several tests, including its use in a pipeline model discretized by the Finite Difference Method. Finally, conclusions and recommendations obtained from the study are presented.
