On Demand PID and Fuzzy Logic Tuning 1996, 1997

Objective: Prototype of the on demand tuning application utilizing relay oscillation technique.

Requirements: Implementation as DeltaV function block, user interface and control application with OPC communication.

Results: As the theoretical foundation was set a need for a working prototype arose to fine-tune algorithms before creating real product. I have implemented function block (working within DeltaV control system controllers) which executed process test part and user interface application controlling test and calculating results. As prototype of function block was up-front coded according to system requirements it was later used as a foundation of real product - DeltaV Tune. Supervisory application was also used in final product after some user interface refinements.
