摘要: This motor control device receives a speed command from an upper layer system control device having a position controller, the motor control device having: a position command estimator that calculates an estimate of a position command on the basis of the speed command and a motor axis position response; and a speed command generator that generates an actual speed command on the basis of the estimate so that an end section of a machine connected to the motor does not oscillate, wherein the actual speed command is output from the speed command generator to a speed controller.

摘要: An estimated value of frequency of a vibration component for automatically adjusting a control unit that suppresses resonance characteristics of a machine is stably and reliably estimated without depending on the magnitude of amplitude of the vibration component and without risk of arithmetic overflow. A motor control device including an automatic adjustment device that adaptively adjusts a controller included in a motor control system based on a frequency of a vibration component superimposed on a response of the motor control system, the automatic adjustment device including a vibration extraction unit that receives the response of the motor control system and extracts the vibration component from the response of the motor control system; a notch filter unit that receives the vibration component from the vibration extraction unit; an encoding unit; a limiter unit that receives an output of the notch filter unit; an adaptive updating unit; and a unit conversion unit.
