  • Publication number: 20060229745
    Abstract: A command generating device includes a command shape calculating unit (5) for calculating an nth derivative command shape which is a fixed multiple of the nth derivative with respect to time of a position command for causing a machine (4) to reach a target position at a positioning time so that a convolution of a velocity command which is the first derivative with respect to time of the position command and the impulse response of a transfer function determined from the frequency of a vibration which occurs in the machine becomes equal to zero, the convolution being calculated over the time period from the positioning time onward, and an associating processing unit (6) for integrating the nth derivative command shape n times with respect to time, and for multiplying the integral result by a constant which associates the position command at the positioning time with the target position so as to determine the position command.
