I’ve known Terry Blevins for years and if I was only half as smart as he is, I’d be happy. Terry was manning the Advanced Process Control booth at Emerson Exchange and he was demonstrating something he’s been working on for 3 years now – Online Batch Process Analytics.
So for the first time in a process automation system, there’s a tool to monitor the quality and predict the endpoint of a batch based on a PCA/PLS developed model. He implemented a really cool technique call Dynamic Time Warping (beam me up, Scotty) which is based on logic used in voice recognition software to remove the time variation in batch to batch runs in developing the models.
Through a presentation layer making use of Microsoft Silverlight, operations and engineering personnel can then monitor, via Internet Explorer, the progression of a batch in real time and not only identify deviations, but quickly determine if the variations will effect the overall batch quality based of critical quality parameters.
