<p><P>PROBLEM TO BE SOLVED: To provide a vibration control device on which an over-current countermeasure is appropriately taken. <P>SOLUTION: A vibration detection signal sg detected in a position whose vibration is to be controlled and an adaptive filter coefficients (Re, Im) are computed. A basic degree adaptive filter coefficient (Re, Im) is then corrected in such a direction that a vibration control current command I<SB>41</SB>is limited within a predetermined range while a basic degree current upper limit exceeding signal S<SB>41</SB>is input based on the basic degree adaptive filter coefficient (Re, Im) to a basic degree adaptive algorithm block 4a in the basic degree adaptive algorithm block 4a in which vibration having a reverse phase to that of the vibration of an engine gn serving as a vibration generating source is generated in the position whose vibration is to be controlled by means of a vibrator 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
