coal and device for regulating the wu00fcrzeabflusses in a lauter tub, characterized by measurement of lu00e4uterdruck or differential pressure, turbidity and konzentrasion. additional measures are speed and amount of the hackvorrichtung and temperatures of the lu00e4uterwu00fcrze and anschwu00e4nzwassers or the extract of the trubes and optional flow rate of lu00e4uterwu00fcrze.it will stellgru00f6u00dfen for height and speed of the hackvorrichtung and flow of lu00e4uterwu00fcrze calculated. the regelungsvorrichtung is preferably realized by mikrorechnersysteme with memory and peripheral devices for the input and output of prozeu00dfsignalen.feature is the use of dynamic models for the prozeu00dfabschnitte of lu00e4uterprozesses in the form of differenzgleichungen or a neural network. the model is based on expert knowledge and physical and technological relationships of the lu00e4uterprozesses and used materials. constructive data of lu00e4uterbottiches.it is for the determination of estimates for lu00e4uterdruck, turbidity and concentration used. the error between the estimated and the measured data is used for model fitting. the model also serves to calculate the current optimized stellgru00f6u00dfe for the flow of lu00e4uterwu00fcrze and stellgru00f6u00dfen for height and speed of the hackvorrichtung.before the issue of a stellgru00f6u00dfe is a predictive calculation of the stellgru00f6u00dfenverlu00e4ufe and determining their effect on the optimierungsgu00fctekriterium carried out. this aktionszeitpunkt is freely selectable or he will because of limits of process parameters or their time derivatives.for the calculation of the stellgru00f6u00dfen is also on the experience and the vortraining comparable south from the past data. the standard procedure behaves like a human expert and learner always adapts to different parameters.it also allows for a calculation of the stellgru00f6u00dfen for the flow of loop, with the aim to achieve homogeneous flow and konzentrationsverhu00e4ltnisse, optionally including concentration measurements in the ringrohren.
