The traditional distributed control system (DCS) is actually a monolithic system, with control distributed across the plant through proprietary networks that began as 4-20 mA signals on twisted pairs of wires. Over the years, the hardware, software and networks have become increasingly sophisticated, digital and powerful, but with few exceptions, control is still done in centralized controller and computer racks. The PlantPAx DCS is naturally different, according to Jim Winter, director, global process business, Rockwell Automation. “PlantPAx evolved from the plant-wide integration of many systems—motion, mechanical safety, process safety, process control—running…

Advanced control for boiler drum level?

A reader asks our experts if it is possible to implement such controls. Find out what they had to say

By Béla Lipták

Q: I read some papers regarding boiler drum level control and almost all mention that, for better performance, we should go for fuzzy logic controllers or model-based controllers instead of traditional PID controllers. However, in those papers, the results are obtained by simulating through Matlab.
