ABSTRACT:
Method and apparatus for controlling pulp refiners where a feed forward algorithm compensates for the time delay in the effective action of the base refiners which are coupled to a high frequency compensating tickler refiner by a machine chest which has a significant time lag. In addition, efficiency of the control system is enhanced by providing a simple control method for a complex series parallel matrix of base refiners where the change of specific energy is easily accomplished by a distribution algorithm.
