摘要： A feedback control system in which the error signal is oscillated by a dither signal having a periodical pattern for oscillating the controlled output. The dither signal comprises a plurality of positive excursions and negative excursions, and at least one of the positive excursions is lower than the others and at least one of the negative excursions is shallower than the others. The dither signal is applied to an actuator to produce a controlled output. A detector senses the value of the controlled output caused by the operation of the actuator. The detector is adapted to produce an output signal in which portions corresponding to at least the low positive excursion or negative excursion of the dither signal are removed when the controlled output deviates from a desired value in different directions.A comparing circuit compares the output signal of the detector with a standard signal value. The output signal of the comparing circuit is signal for detecting the removed portions. The output signal therefrom is fed to a shift signal generating circuit for shifting the dither signal for correcting the deviation of the controlled output. An amplitude control circuit is provided for reducing the amplitude of the dither signal when the comparing circuit produces a signal representing a condition of the controlled output in a central range with respect to the desired value so that the amplitude of the controlled output can be reduced.
