Simple PI and PID Controllers Tuning for Monotone Self-Regulating Plants

Abstract The paper describes an original analytic-experimental approach to simple digital and analog PI and PID controllers tuning for monotone self-regulating plants with a time delay. Values of adjustable controller parameters ensuring a marginal monotone control process are determined analytically, and the gain of the controller is tuned experimentally so that an overshoot of a step response of control system corresponds to the concept of the designer. The approach is taken from the dynamics inversion method and its use is shown in the examples.
