21 Function Description PI control Dosage 100% at Example ph With a throughput neutralization which is intended to regulate the ph 7.0, arises at constant throughput with a pure P control a deviation of 1.2 ph, due to the flow rate and pump capacity. That is, the lye dosing levels off at 40%, the ph value displayed on 5.8. Without I component is now takes the limits for GW and GW move to to arrive at a dosing performance of about 40% at ph 7.0. Nothing else makes the I component. He moves the dosing limits of 0 and 100%. Pump activity 40% Only P-regulation 0% ph 3.0 ph 4.0 ph 5.0 ph 6.0 ph 7.0 ph 8.0 LI ph 5.8 LI Dosage 100% 0% 25% ph 3.0 ph 4.0 ph 5.0 ph 6.0 ph 7.0 ph 8.0 PI-regulation Through the I-component is the control on the right track. But not yet arrived. In this case, a constant offset to the dosing limits GW and GW added. ph 6.6 LI LI

22 Dosage 100% Oops, something added too much. offset - 43% PI-regulation 0% ph 3.0 ph 4.0 ph 5.0 ph 6.0 ph 7.0 ph 8.0 ph 7.1 The speed of the reaction time can be preselected in 1% / sec. If a constant acid supply is there, then you can go on slowly. Thus, you only have a small overshoot. But when a very different inflow of flow rate and ph-value is present, you should respond quickly. That the reaction time must be fast. In return, however, one takes thus a bigger Overshoot in purchasing. Dosage 100% And now turn back. offset + 36% PI-regulation 0% ph 3.0 ph 4.0 ph 5.0 ph 6.0 ph 7.0 ph 8.0 ph 6.8
