Diseño, simulación y control en lazo cerrado de temperatura en hornos por medio de convertidores estáticos: diseño, simulación y control de temperatura de un horno eléctrico empleando resistencias-control electrónico al lado AC.

Abstract

The present curricular integration project, is shown the design and simulation of the temperature control of an oven using resistances. A short explication about the industrial ovens or electric ovens and its applications in the industry is made. Moreover, an analysis about the topologies of the static converters of AC/AC energy is made, in order to choose the project’s right converter. To design the controllers, first the electrical system and the thermic system are mathematically modeled, and with these models the PI controllers for the cascade control system to control the temperature. Current, power and temperature open and closed loop responses are obtained. To make possible the interaction between the user and the electric system, a human-machine interface was designed through Python software, where each control loop references can be entered and the desired control loop can be selected
