RELAY-TUNED FINITE SPECTRUM ASSIGNMENT CONTROL OF TIME-DELAY PROCESSES

In this paper, the finite spectrum assignment (FSA) control of first-o rder time delay processes is addressed, including stable and unstable processes. Controller design rules are provided and they require only specifications of classical closed-loop desired properties from the us er. Astrom's relay auto-tuning is used to yield input-output transient s in the closed-loop, from which the parameters of the model may be ex tracted. The stability of the so auto-tuned FSA system is discussed an d simulation examples are included for illustration. (C) 1998 Elsevier Science Ltd. All rights reserved.
