The Application Of Pridictive Control In Chemical Dosing System For Waterworks

Since predictive control can directly deal with the pure lagged object, and it issuitable for the big lagged system. Predictive control also has good ability fortracking and stability. The chemical dosing system for waterworks has the problem oflagging, if we use expert and proportional control, it can't reach the expected effect.So we add predictive controller in the dosing system, and it can eliminate themistakes which are caused by lagging. This article introduces dynamic matrix controlwhich is supposed to be used in the chemical dosing system of waterworks. At lastwe shall emulate the respond of the system in order to know the effect.
