Abstract: As a consequence of the strategy of choosing the control parameters (that is, tuning gain, process feedback gain and three model parameters – steady-state gain, settling time and time delay), the proposed P-IMC algorithm enjoys a quasi-universal practical applicability. The main purpose of this paper is to analyse how the weighting coefficient α of the proportional component P of the P-IMC algorithm may affect the control quality, thereby providing useful information to the manufacturer and human control operator. Moreover, this paper presents certain useful results regarding the influence and effect of the parameters of the proposed model upon the control performance of a control system.

Keywords: Practical control algorithm, Internal model, Robustness, Tuning gain, Model steady-state gain, Model settling time, Model time delay, Process feedback gain.
