Abstract
In this paper, the tuning method, based on characteristic areas and Magnitude Optimum (MO) criterion for some unstable processes is presented. The proposed approach is to use inner compensator, of the first or the second order, to stabilise the process. The stabilised process is controlled by 2-DOF PI controller, tuned by using MOMI or DRMO tuning method (depending on desired tracking or disturbance-rejection performance). The proposed method was tested on five linear process models. The responses were relatively fast and without oscillations, all according to the MO criterion.
