Industrial Adaptive Controllers Based on Frequency Response Techniques

Hägglund, Tore LU and Åström, Karl Johan LU (1991) In Automatica 27(4). p.599-609
Abstract
This paper describes several adaptive techniques based on frequency response analysis, which are used in industrial controllers. Automatic tuning is used to obtain PID controller parameters, to build up gain schedules, and to initialize adaptive algorithms. A simple adaptive feedback algorithm which is based on the idea of tracking a point on the Nyquist curve is presented as well as an adaptive feedforward procedure. The adaptive techniques have been implemented in various industrial products. Industrial experiences from using the controllers are summarized in the paper.
