A generalization of the previously presented KLV method for the autocalibration of PI controllers (based on one frequency experiment) is realized so as to extend its validity domain. The underlying process models and PI designs are given. The new autocalibration procedure includes two frequency experiments on the plant (closed‐loop relay experiments) to extract the process dynamics. Comparisons with other tuning methods are presented. Simulations and experiments on a real plant illustrate the feasibility of the proposed approach.
