Abstract— In place of popular Smith-type predictors, this paper proposes switching to control based on the predicted value of the controlled variable. This transition is possible for both new and existing automatic control systems with classic linear controllers. By using a predict for standard algorithms (PI, PID), control quality is significantly improved, while simultaneously increasing the stability margin. Calculations conducted in this paper for single-loop and dual-loop control systems showed that using a predict leads to a reduction in the range of variation of the controlled variable by up to three times, and the effectiveness of the proposed method increases with increasing complexity of the control structure. This paper develops research into manual tuning of a control system using a single parameter—the forecast time. The possibilities of such control are demonstrated by modeling various controlled channels of medium-power power boilers.
