Improved Relay Autotuning using Normalized Time Delay

Abstract (Swedish)
The relay autotuner provides a simple way of
finding PID controllers of sufficient performance. By using
an asymmetric relay function the excitation of the process is
improved. This gives better models, and hence a better tuning,
without increasing the time consumption or complexity of the
experiment. Some processes demand more accurate modeling
and tuning to obtain controllers of sufficient performance.
These processes can be singled out by their normalized time
delays and be subject to further modeling efforts. The autotuner
proposed in this paper provides a simple way of finding
the normalized time delay from the experiment, and uses it
for model and controller selection. The autotuner has... (More)
