Design of Performance-Driven PID Control Systems based on Control Performance Assessment

Abstract

In the challenge to manufacture high quality products for less, it is necessary to regularly monitor performance of control loops that regulate the quality variables of interests. This paper introduces two methods of performance-driven PID control systems whose PID parameters are re-tuned based on the controller performance assessment. The re-tuning is based on the self-tuning control mechanism. The effectiveness of these schemes are demonstrated by the experimental studies.
