| Abstract: | This paper centers on on-line relay automatic tuning method of PID regulators,The parameters of the process model are estimated from the limit cycle oscillate under relay feedback andthus the parameters of the PID regulators are determined. Formulas for estimating the parameter based on the input and output signals of the process are presented. |
