- 摘要：
PROBLEM TO BE SOLVED: To provide an operation correcting device capable of eliminating a noise signal that temporally changes.
SOLUTION: A meal support apparatus is provided with: a force sensor for outputting a main signal corresponding to operation to a manipulator and an input signal IN including a tremor signal an inputting means 15 in which the input signal IN outputted from the force sensor is inputted and a tremor frequency estimating means 42 for determining an estimated frequency f
t (i) corresponding to a frequency at each time of the tremor signal that temporally changes by updating a tap coefficient for minimizing an output of the input signal IN inputted to a notch filter to which an all-pass filter APF is applied as a tremor elimination system 18. Then, by a cutoff filter determined on the basis of the estimated frequency ft (i) determined by the tremor frequency estimating means 42, the tremor eliminating means 44 eliminates the tremor signal from the input signal IN to generate an output signal OUT.COPYRIGHT: (C)2010,JPO&INPIT
