Abstract

PURPOSE:To minimize an influence on a control system by suppressing the oscillation of the control system by subtracting the deviation between an operation command signal to a controlled system and feedback signal from the controlled system as the correction quantity of the FB signal. CONSTITUTION:Manipulated-variable command X is inputted to controlled system 14 via comparison part 10 and forward transmitting circuit 12, and FB signal Y from system 14 is negatively fed back to a control system via manipulated-variable detection part 16 and comparison parts 18 and 10. Signal Y is inputted to amplification part 20, where the input signal is held at the same level with signal X by correcting control deviation (epsilon), and its output signal YA is inputted to deviation detection part 24. Detection part 24 obtains difference signal YA-Ytheta between signal YA and output Xtheta of phase conversion part 22 receiving signal X as an input, and then inputs it to blind sector part 26. Blind sector part 26, when the deviation surpasses blind sector set range V0, judges that an oscillation state and outputs oscillation suppression signal Yalpha to comparator 28 and comparison part 18. Further, signal Yalpha is subtracted from signal Y and signal Y-Yalpha is fed back to the control system as an FB signal to suppress the oscillation.
