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.
