摘要： A servo control device includes a follow-up control unit that controls a control target that drives a mechanical system by a motor, a command function unit that has input therein a phase signal θ indicating a phase of a cyclic operation performed by the control target, and that calculates a machine motion command according to the phase signal θ by a preset first function, a second derivative unit that uses a second function obtained by second-order differentiating the first function with respect to the phase signal to calculate a value of the second function according to the phase signal as a second-order differential base signal, a correction-value computation unit that computes a first command correction value for correcting the motor motion command by using a product of a square value of the phase velocity, the second-order differential base signal, and a first constant, and a correction-value addition unit that calculates the motor motion command based on an added value of the first command correction value and the machine motion command.
