FIELD: electronic engineering; automation.
SUBSTANCE: invention relates to electronic engineering and automation. A feedback system containing a differential amplifier, a regulator, an amplifier with a variable gain and an object connected in series in a closed loop, and the positive input of the differential amplifier is the input of the system, its negative input is connected to the output of the object, which is the output of the system, while an error signal analyzer is introduced in it, connected between the output of the differential amplifier and the control input of the variable gain amplifier.
EFFECT: reduced dynamic error.
