Abstract
Perfeccionamientos en sistemas de control del funcionamiento de una caja de cabeza de máquina de papel, que comprenden captadores de medida de los parámetros del proceso y de los accionadores de los órganos del proceso, caracterizados porque al menos la mayoría de los captadores se conectan funcionalmente a un número al menos igual de accionadores por mediación de un órgano de control centralizado multivariable que permite controlar cada accionador por la toma en cuenta y el tratamiento de la información de mediad de un captador ó de varios captadores, y hacer actuar la información de medida de cada uno de los captadores conectados funcionalmente a los accionadores sobre uno ó varios de estos accionadores de modo a conseguir una acción resultante en la que, solo el parámetro medido por este captador quede influenciado, mientras que las repercusiones secundarias sobre los demás parámetros quedan neutralizadas.
