Diseño e implementación de cuatro esquemas de control modificados basados en el predictor de Smith en una tarjeta embebida, aplicados a dos modelos simulados que presentan retardo: un tanque de mezclado y un reactor de agitación continua (CSTR)

Abstract

The control schemes based on the Smith predictor help to improve the response of industrial processes that have high and variable time delays. It is for this reason that the objective of this project is to design and implement four modified control schemes based on the Smith predictor in an embedded board, which are to be applied to two simulated non-linear models with a high time delay. The Hardware In the Loop simulation is used, which allows to verify the operation of the different control schemes implemented against different tests without produce damage to physical instruments such as: sensors, transmitters, final control elements, etc. Additionally, the construction of a module that allows selecting the implemented control scheme and making reference changes and disturbances to the process is carried out. To observe the variations made by the user, the development of a graphical interface is carried out which allows to visualize in a friendly way each of the variables of interest of the process and based on the performance indices ISE and TVu helps to make a comparison between the different control schemes.
