FOLLOW-UP SYSTEM OF AUTOMATIC CONTROL WITH COMPENSATION FOR NONMEASURABLE DISTURBANCES Russian patent published in 1995 - IPC

FIELD: automatic control systems. SUBSTANCE: follow-up system comprises a setter 1, first comparator 2, amplifier 3, sequential correcting device 4, power amplifier 5, motor 6 and working tool 7. The output of setter 1 is connected to the first input of the first comparator 2, the output of the amplifier 3 is connected to the first input of the second comparator 10 and the output of motor 6 is connected via a parallel correcting device 8 to the second input of the second comparator 10 and, across a feedback sensor 9, to the second input of the first comparator 2. The system also comprises a signals identification and shaping unit 12 intended to compensate for disturbances. Said unit incorporates first groups of scale amplifiers 13, first integer adders 12, second integer adders, second adders, second groups of scale amplifiers 17, third group of scale amplifiers, and a third adder. EFFECT: improved design. 2 dwg
