Concepts and implementation of PID controllers in a smelting furnace steel

La importancia en la industria de tener los procesos debidamente controlados para evitar que estos salgan de su respectivo punto de operación ha llevado a desarrollar distintos sistemas de control, en el presente artículos se describe uno de tantos sistemas, los controladores PID (Proporcional, Integral, Derivativo). Estos controladores se encargan de mantener un proceso en un estado de trabajo estable, cuando se presenten variaciones controladas o aleatorias el sistema por medio de una función de transferencia y los parámetros de sintonización del controlador se encargaran de regresar el sistema a su respectivo punto de operación. Además se analizaran distintas gráficas generadas por medio de la herramienta de SIMULINK de MATLAB para facilitar la comprensión de los conceptos y del caso en estudio, la identificación, sintonización también son parte de dicho estudio. The importance in the industry of having accurately controlled process to avoid that they run out of their specific operating point, has led to develop different control systems, the following article describes one of many systems, the PID drivers (Proportional, Integral, Derivative). The importance in the industry of having accurately controlled process to avoid that they run out of their specific operating point, has led to develop different control systems, the following article describes one of many systems, the PID drivers (Proportional, Integral, Derivative). These drivers are in charge to maintain a process in on stable state of work, when there are controlled or random variations of the system by a transfer function, the tuning parameters of the driver are in charge to bring back the system at its respective operating point. Moreover, different graphics generated by the SIMULINK tool of MATLAB will be analyzed to facilitate the concepts comprehension and in this study, the identification and tuning are also on important part of it.
