DYNAMIC MATRIX CONTROL OF DIAPHRAGM-TYPE CHLORINE CAUSTIC ELECTROLYSERS

Dynamic matrix control (DMC) is now widely used in industrial control, and when properly applied results in significant savings due to impro ved efficiency and reduced off-spec product. The objective of this pap er is to implement MIMO DMC on a simulated diaphragm-type chlorine/cau stic electrolyser. A comparison between the MIMO DMC and traditional m ulti-loop SISO PID control strategy shows greatly improved controller performance and cell efficiency using DMC, which will result in reduce d operating costs and increase cell diaphragm lifespan.
