FEEDBACK SYSTEM Russian patent published in 2016 - IPC G01R23/02 

FIELD: electronic equipment.

SUBSTANCE: invention can be used in digital and analogue automatic control systems, control and stabilization of different physical quantities (temperature, pressure, efficiency, speed, etc.) with feedback, used in various industries and in scientific research for control objects susceptible to vibrations. Feedback system comprises series-connected in closed circuit first regulator, switch, object, subtractor, connected through its negative input, also containing second controller, connected at output of subtracting device. Positive input of subtractor is input of system, and output of control object is output of system. Besides, there is error signal analyzer connected between output of subtractor and control input of switching device, and output of second controller is connected to second input of switching device.

EFFECT: technical result consists in reduction of dynamic error.
