摘要
A feedback system control device includes an adder producing a control signal from a feed forward signal and a correction signal. A system which processes the control signal drives the feedback system, which produces an output signal. A feed forward circuit, e.g., a four- pole network, receives the input signal and produces the feed forward signal. An error amplifier in the corrector processes the difference between the input signal and the output signal to produce an error signal. A corrector produces the correction signal from an input signal and this error signal. Two processors in the corrector each receive the error signal and produce respective modification signals between which there is a relative phase shift. An adder sums the modification signals to produce the correction signal.
