ABSTRACT:
A high-performance and high-band feedback controller which provides a state observer in which an amount of state or an amount to be controlled outputted from a detector part and an amount of operation are input signals, presumes the amount to be controlled which is closer to a true value, can compensate for deviations from desired characteristics such as a mechanical resonance characteristic and a delay time characteristic in a high frequency band of an object to be controlled and a detector part by feeding back this presumed amount, and, further, can eliminate noise mixed into the detector part by setting the band of the state observer lower than a frequency of the noise mixed into the detector part.
