Problems of modelling Proportional-Integral-Derivative controller in automated control systems

Abstract

The actual task of modelling automatic control systems is to use control algorithms that include some function that limits the output signal. Proportional-integral-derivative (PID) controllers are used to control dynamic processes with variable at wide limits parameters and uncontrolled violations in automated process control systems. Despite the wide distribution, this type of controllers is not easy to configure. In article the problems of modelling proportional-integral-derivative controller are discussed. The methods of combating the effect of integral saturation are studied. The results of using algorithms of combating the effect of integral saturation are represented.
