Techmation Protuner: A Timesaving Loop Tuning Device for Improved Process Control.

摘要

This document describes the Techmation Protuner Model 1100. The Protuner is a compact device for analyzing a process or process control system. This device can tune process controllers, determine process parameters (dead-times, steady state gains, dynamic gains, time constants), and produce Bode and Nichols diagrams. It is fast, portable, user friendly, and compatible with either electronic or pneumatic instrumentation. The Protuner was bought by the Analytical Development Division (ADD) of the Savannah River Laboratory in 1986. This report is the result of over a year of testing and evaluation on processes throughout the Savannah River Plant. This report includes: A description of the Protuner hardware; A description of a typical operating session; Examples typical of the successes achieved by using the Protuner; A specification sheet; A discussion of the tuning algorithms one can use with the Protuner; and A discussion of criteria for choosing the proper controller modes. The Protuner has been used to bring under control processes that had been thought controllable only with advanced strategies, as well as to significantly improve the operation of loops that had been thought to be well-tuned. Information on borrowing ADD's Protuner, arranging demonstrations, and purchasing information is provided. 4 refs., 18 figs. (ERA citation 13:057152)
