PROBLEM TO BE SOLVED: To provide a vibration removing system tunable in a short time. SOLUTION: The method for determining, in a vibration removing device comprising a vibration removing base supported by a plurality of active actuators and a control means damping-controlling the active actuators according to a predetermined control function, a plurality of set values for the control function by genetic operation comprises a chromosome formation setting step of converting a value within the allowable range of each set value for the control function to a binary initial value of a predetermined bit number to generate a chromosome; an evaluation step of substituting the initial value to the control function, giving a disturbance to the vibration removing base to make the control means perform control operation, and measuring the damping characteristic to calculate an evaluation value; a selection step of selecting chromosomes of the number of the set values from chromosomes having evaluation values within a predetermined range; and a crossing step of selecting two or more chromosomes from the selected chromosomes, and replacing a part of bits of each chromosome by the bits of the other chromosome to cross them. The evaluation step, the selection step and the crossing step are repeated to determine the set values. COPYRIGHT: (C)2005,JPO&NCIPI
