摘要
A method for controlling a process to produce refiner pulp, where the method is controlled with a multivariable control algorithm, where at same time two or more of the following quantities are used as control variables; a) mass flow of wood of the speed of revolutions of the feeding screw, b) width of the refinin split; c) speed of revolutions of the rotor or its peripheral speed, d) rotation force of the motor. In the system at least two measuring variables are used of which one is tear, which is coupled to at least one of the named control variables a), b), c) or d).
