Abstract
PURPOSE: To obtain a freeness controlling device inhibiting the deterioration of the control of the refiner driving motor by controlling the motor with the operating out put obtained from the control calculation of the deviation between the predetermined value given by a time integration technique and the observed value given as time integration of the product of flow signal and freeness signal. CONSTITUTION: A setting mean 123 supplies setpoint signal QFs increasing in a constant gradient in which time integrated value for a batch of time reaches to the SVs (the desired value of the freeness integration), to a controlling mean 122. The operating output MV is transmitted by carrying out the control operation on the deviation of these integration such as production, integration, differentiation or the like, on time integration value of the product FQ of the observed freeness F and the observed flow rate Q and the time integration value of QFs is calculated by the controlling mean 122. Adding machine 13 supplies the operating output MV' obtained by adding the operating output MV and concentration correction output MC, to the motor 6.
