Chementator: Faster predictive control  

By Gerald Ondrey |

Cutler Technology Corp. (San Antonio, Tex.; www.cutler-tech.com) has launched ADMC 64, its most-advanced model-predictive controller ( CE, November 2005, p. 15). With 64-bit resolution, the device easily handles 600 coefficients with calculation times under ten seconds (on an Intel quad PC running Microsoft Server 2008), solving problems with 240 manipulated variables and 554 controlled variables. In contrast, olefin plants, for example had to use either a composite linear program (LP), or a number of coefficients had to be reduced to under 300 with calculations intervals of every two minutes or longer, says the firm.
