    El artículo presenta un método para la identificación de plantas de primer y segundo orden con retardo usando controladores reseteados en ausencia de perturbaciones. El método se basa en el cumplimiento del principio de equilibrio armónico, lo que implica el uso de una aproximación del controlador reseteado mediante su función descriptiva. Para la realización de este trabajo se ha elegido el controlador FORE (First Order Reset Element) con banda de reset porque es el controlador reseteado que posee todas las características intrínsecas de este tipo de controladores y presenta una función descriptiva que depende de la amplitud y frecuencia de la señal sinusoidal de su entrada. Por otro lado, el que el comportamiento de este controlador dependa de la anchura de la banda de reset que se haya fijado permite estudiar el impacto de este parámetro en el proceso de identificación y en su precisión.

    The article presents a method for the identification of first and second order processes with time delay using reset controllers in the absence of disturbances. The method is based on compliance with the method of harmonic balance, which implies the use of an approximation of the control reset by its describing function. The FORE controller (First Order Reset Element) with fixed bandwidth has been chosen because it is the easiest reset driver that possesses all the inherent characteristics in this type of drivers and its descriptive function depends on the amplitude and frequency of its sinusoidal signal input. On the other hand, the fact that the behavior of this reset driver depends on of its reset band allows studying the impact of this parameter in the identification process and in its accuracy.
