Research Activities on PID Gain Tuning based on Closed-loop Operation Data

—Working Example of Relaxed Industry-academia Collaboration—

Abstract

The paper introduces recent activities on PID gain tuning based on closed-loop operation data. The approach tries to provide PID gain tuning tools only from process input and output data. Such tools are strongly required in the industrial fields because a huge number of PID control loops have to be tuned by a few control engineers. Extended Fictitious Reference Iterative Tuning (E-FRIT) and further researches on E-FRIT have been shown, and future directions on the topic are examined. Finally, the paper discusses how we should proceed with industry-academia collaboration through the research activities on E-FRIT.
