This paper proposes an on-line relay automatic tuning method of PID regulators, in which the parameters of the process model are estimated from the limit cycle oscillation under relay feedback and thus the parameters of the PID regulators are determined. Formulas for estimating the parameters baaed on the input and output signals of the process are presented. The experiences obtained from experimentation have shown the proposed method to work well and to be simple and reliable.
