Benefits of Fuzzy Logic for Advanced Process Control

Summary

Rockwell Automation has released a new white paper exploring fuzzy logic and how it helps engineers solve nonlinear control problems commonly found in process applications. Fuzzy logic, which mathematically emulates human reasoning, provides an intuitive way to design function blocks for intelligent control systems, advanced fault detection and other complex applications. Control systems deploying fuzzy logic can improve the management of uncertain variables, such as temperature fluctuations.

The paper, “Nonlinear Control and Decision Making Using Fuzzy Logic in Logix,” provides best practices for designing with fuzzy control and examines its benefits compared to conventional control methods. In addition, the paper outlines how to develop fuzzy logic algorithms for the Allen-Bradley Logix family of programmable automation controllers, using the RSLogix 5000 FuzzyDesigner software package. The paper introduces the newest features of the RSLogix 5000 FuzzyDesigner software package, such as fuzzy logic add-on instructions. These features reduce development time, improve maintainability and ease setup of fuzzy logic programs, all while helping to protect intellectual property.

“At its heart, fuzzy logic is a way to embed an engineer’s experience into the control system,” said Jeffrey Shearer, software product manager, Rockwell Automation. “It can significantly improve response to fast-changing variables, so we are actively incorporating fuzzy logic into our Logix family of controllers, giving users a common control platform for their discrete, batch and advanced process control needs.”
