|発明の名称||BATTERYLESS METHOD AND APPARATUS FOR MEASURING ACCELERATION BY OSCILLATING GENERATOR|
PROBLEM TO BE SOLVED: To provide a batteryless method and an apparatus for measuring acceleration by an oscillating generator and capable of accurately estimating the acceleration of vibration.
SOLUTION: When oscillation is added to the oscillating generator 1, a voltage is generated in coils 14 and 15. The generated voltage is measured by a voltmeter 4. A force to be provided for a magnet is computed by a digital computer 5 on the basis of its value through the use of a disturbance-accommodating control theory, and a current is controlled by an electric/electronic circuit 3 according to this. An estimate value of the acceleration of input oscillation is determined by the digital computer 5 by inverse operation from the generated voltage. A force given to the magnet by the current flowing through the coils 14 and 15 and a value of the generated voltage generated by it are compared with a value of a generated voltage computed on the basis of a relational expression between a force given to a magnet by a current flowing through a coil and a generated voltage to determine their difference. The estimate value is corrected by an observer in consideration of this to estimate an estimate value xeα of the acceleration of the oscillation input to the oscillation power generator 1.
