Utilizing DeltaV Advanced Control Innovations

Several Meet the Expects workshops are schedule on the last day of Emerson Exchange. As part of this effort, Willy Wojsznis and I co-hosted a workshop this year titled Utilizing DeltaV Advanced Control Innovations to Improve Control Performance. In this workshop we explore and discuss innovative features of the DeltaV PID and embedded Advanced Control products that can be applied to improve control performance. In particular, we address PID options that enhance cascade and override applications and allow effective single loop control using a sampled or wireless measurement. We discuss how DeltaV MPC may be easily applied with no changes in the existing control strategy. Also, we mentioned the benefits of a future tool that is currently being tested in two field trials – continuous data analytics. Both sessions of this workshop on November 4th, 2013 were well attended. A picture from one of the workshops is shown below.

In the workshop, we recommended that the audience read the books Advanced Control Foundation – Tools, Techniques, and Applications and Control Loop Foundation – Batch and Continuous Processes to learn more about DeltaV control features. Also, in the workshop we showed the web sites that go with these books – ControlLoopFoundation and AdvancedControlFoundation.
