Abstract
According to an embodiment, a control apparatus includes a shaper and a compensator. The shaper receives a first target value in position control of a controlled object and generates a second target value which changes substantially rampwise over a time equal to or shorter than a period corresponding to one of resonance frequencies of the controlled object until the second target value becomes equal the first target value. The compensator compensates for a control signal, used for controlling the controlled object, based on the second target value.
Claims9
A control apparatus comprising:
- a shaper that receives a first target value in position control of a controlled object and generates a second target value which changes substantially rampwise over a time equal to or shorter than a period corresponding to one of resonance frequencies of the controlled object until the second target value becomes equal the first target value;
- and
- a compensator that compensates for a control signal, used for controlling the controlled object, based on the second target value.
A tunable filter apparatus comprising:
- a substrate;
- a plurality of resonators that are formed on a first surface of the substrate by patterning, using a conductive material;
- a plurality of characteristic tuning members that comprise at least one of a dielectric material, a magnetic material and a conductive material;
- a plurality of tunable mechanisms that support the characteristic tuning members such that the characteristic tuning members face the resonators and that control the characteristic tuning member based on a control signal,
- a shaper that receives a first target value in position control of each of the characteristic tuning members and generates a second target value which changes substantially rampwise toward the first target value over a time equal to or shorter than a period corresponding to one of resonance frequencies of the characteristic tuning member;
- and
- a compensator that compensates for the control signal based on the second target value, wherein
- the control signal changes in accordance with a desired filter characteristic, and
- the tunable mechanisms individually move the characteristic tuning members in a common direction in response to a change in the control signal.
