Improved relay auto-tuning with static load disturbance
In the presence of static load disturbance, a relay auto-tuning experiment shows significant errors in estimating the ultimate gain and period. This paper shows how to overcome the problem without any information on the static gain of the process and how to obtain process gain from one relay experiment.
