  • Command generation device and command generation method to control motor
    Patent number: 11914343
    Abstract: A command generation device to control a motor includes command input circuitry configured to receive a first command, first intermediate data calculation circuitry configured to calculate first intermediate data based on the first command, delay time setting circuitry configured to determine a delay time based on the first command, second intermediate data calculation circuitry configured to calculate second intermediate data by smoothing the first intermediate data based on the delay time, and command output circuitry configured to calculate, based on the second intermediate data, a second command according to which the motor is controlled. A first time period during which positioning the motor based on the first command is completed when the first intermediate data is smoothed is longer by the delay time than a second time period during which positioning the motor based on the first command is completed when the first intermediate data is not smoothed.
