ASUtune: A Program for Integrated System Identification and PID Controller Design

Abstract

This paper describes ASUtune , a MATLAB program for combined identification and PID controller design. By integrating identification with PID controller design, the method displays functionality that is often demanded by the practicing engineering community. The major steps in this integrated methodology are, experimental design and execution, high-order ARX estimation, and control-relevant model reduction leading to models that comply with the IMC-PID tuning rules. These PID tuning rules are compatible with the Honeywell TDC 3000 distributed control system.
