Resumen-La transformada ondita (TO) se puede usar en el análisis de señales no periódicas, originadas en perturbaciones tales como sobretensiones, huecos, cambios de frecuencia, cortes, flicker, etc. En mediciones de la potencia, energía y valores eficaces de tensión y corriente, la TO presenta la ventaja de proporcionar una distribución de la pote...

Background Artificial pancreas design using subcutaneous insulin infusion without pre-meal feed-forward boluses often induces an over-response leading to hypoglycemia due to the increase of blood insulin concentration sustained in time. The objective of this work was to create an algorithm for controlling the function of insulin pumps in closed-loo...

In geometric control model based methods, it is well known that if a nonlinear system has its relative degree equal to the number of states in the neighborhood of a point of equilibrium, thus it is possible to perform a coordinate transformation and a state feedback that transforms the nonlinear system into a linear and controllable one. Stabilizat...

El control vectorial de máquinas eléctricas puede considerarse como un caso particular de los métodos de control geométrico diferenciales desarrollados por Isidori, Sartri y otros. Estos métodos se basan en un cambio de variables llamado difeomorfismo que convierten a un sistema no lineal en uno lineal y controlable. Sin embargo su desventaja es la...

Flat systems are a generalization of linear systems, but the techniques used for controlling flat systems are much different than many of the existing techniques for linear systems. In this paper we present the flatness-based control of blood glucose regulation in human system. A non-near model, he Bergman Minimal Model, is used o represent he dyna...

This project mainly consisted of the design and construction of a Proton Exchange Membrane Fuel Cell (PEMFC) which makes up a stack, and the performance of experimental tests on measuring the electricity generated with a variable demand in low power applications. This was done to characterize and measure the various electrical and physical paramete...

El tratamiento de la enfermedad conocida como Diabetes Mellitus insulino-dependiente o Diabetes Tipo I (DMID) se puede ver como el agregado de un lazo de realimentación externo que reemplaza total o parcialmente la función del páncreas como órgano regulador de los niveles de glucosa en sangre. En la actualidad el desarrollo de un sistema de control...
