En este trabajo se define la arquitectura de un núcleo de control (NC) que permite ejecutar aplicaciones de control empotradas, así como los principales problemas que soportan su desarrollo. Se propone la estructura de los datos y los servicios que debe proveer este núcleo para aplicar varias estrategias de control que pueden ser utilizadas para garantizar seguridad, fiabilidad y economía en sus operaciones. En el trabajo se presentan dos ejemplos que ilustran el uso del nućleo de control.
