Practitioners of every age know that tuning very slow processes presents a challenge when faced with rigid time constraints. Specifically the time needed to perform the requisite bump
tests isn’t always practical. In order to tune such loops quickly some practitioners have
successfully applied a hybrid approach. While this approach won’t be found in university
textbooks, it has been proven to do the trick in a range of situations. Skeptical? Read on.
Evaluating the overall performance of many individual control loops, with interactions among them, under a variety of operating conditions is key to process optimization. Analytical tools are making this easier.…Read More
There is a growing number of CLPM solutions on the market that offer a range of capabilities.
Understanding which product suits your unique monitoring and diagnostic needs can present
challenges. As with other automation technologies there are numerous aspects of CLPM that should be considered prior to writing your request for proposal and making an investment. This
article offers basic guidelines for evaluating and selecting an appropriate CLPM solution.
Control loop performance monitoring solutions were supposed to facilitate optimization of a plant’s PID controllers. Difficulty with real-world process data and limits on their ability to provide meaningful recommendations hampered effectiveness. Those speed bumps have been removed and real-time optimization is now on the fast track.Read More
