CONTROLLER FOR FEEDBACK SYSTEM Russian patent published in 2009 - IPC G05B11/14 

FIELD: instrument making.

SUBSTANCE: invention is related to electronic engineering and automatics and may be used in digital and analog automatic systems of control, regulation and stabilisation of various values (temperature, generation frequency, speed, etc) with feedback, used in various industry fields and scientific research, where automatics is used. Controller for feedback system comprises serially connected subtracting device and subsequent channel that connect inlet and outlet of controller that is introduced between inlet of the whole system and object inlet. It also comprises serially connected bypass channel and summator, besides inlet of bypass channel is connected with outlet of subsequent channel. Outlet of summator is connected to inverting inlet of subtracting device, and its second inlet is connected to outlet of device. Besides amplification of parallel channel in the area of high frequencies considerably exceeds amplification of object, and in the area of low frequencies it is considerably lower than object amplification.

EFFECT: higher accuracy and efficiency with preservation of stability.
