Resumen: En este trabajo se plantea una estrategia de control enfocada en la producción de crudo en un sistema de bombeo electro-sumergible, utilizando un controlador difuso implementado en un PLC. Para la etapa de identificación del proceso se adquiere los datos de un pozo de producción de crudo modelando el sistema y así estableciendo las variables que determinan el proceso. Se realiza el diseño y ajuste del controlador difuso por Matlab, para implementar el controlador difuso utilizado el software Fuzzy Designer y un PLC ControlLogix L61. Palabras clave: Identificación y modelado de sistemas, Control difuso, control PID, PLC, producción de crudo.
En el presente estudio se describe un análisis general de los distintos mecanismos y procedimientos aplicados al análisis del aliento para diagnostico precoz de diferentes enfermedades.En gran parte de estos métodos se da a conocer que la mayoría del contenido del aliento exhalado está formado por una gran variedad de compuestos (por ejemplo: nitrógeno, oxígeno, de dióxido de carbono, agua, gases inertes, entre otros). Las fuentes de estos volátiles son los componentes atmosféricos que se originan a partir de muchos disolventes y productos a base de petróleo, y otros compuestos orgánicos volátiles que se generan como resultado de los procesos bioquímicos del cuerpo.En la mayoría de los estudios encontrados describen los diferentes sistemas de muestreo y dispositivos de medición, de los cuales en este estudio se referencian los que son aplicados a enfermedades terminales (por ejemplo, el cáncer).
The survival of living organisms is accomplished through regulatory behaviors. In the case of the specialist Namibian sand-diving lizards, those behaviors are modulated not only in response to external events in their immediate ecological context but also to satiate their internal drives. Both homeostasis and allostasis are endogenous processes responsible for maintaining the internal stability of animal physiological variables, in which allostasis serves as a controller coordinating multiple homeostatic subsystems. By performing homeostatic and allostatic regulation, the desert-adapted lizard can avoid extreme temperatures while being able to acquire limited resources. Moreover, a living organism can make behavioral adaptations to cope with chronic stressful situations presented by its unstable environment.Yet how multiple internal states are processed and calibrated during those processes has not been fully clarified due to how inconsistent "allostasis" is understood and applied in numerous researches. We concentrate allostatic control to behavioral adaptation without anticipation to highlight that homeostasis and allostasis offer complementary procedures to withstand immediate instability. This study integrates homeostatic and allostatic regulatory mechanisms based on interoceptive and exteroceptive cues into a simulated mobile robot replicating the lizard's sand-diving and foraging behaviors. To implement drive competition and conflict resolution in the animal's brain, we propose a computational model based on the interaction between the brainstem's medial Reticular Formation and the hypothalamus. Such a bio-inspired system is capable of action selection, and thus, can generate complex behaviors upon stimuli received from both the environment and the agent's internal states.Finally, we evaluate the robot's performance under capricious environmental settings. Our results support a dynamic, reconfigurable hierarchical organization of internal drives as an essential feature of sufficient regulation that ensures a healthier constitution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
