Abstract
The control device in a linear motor system calculates a current command value for the stator based on a first speed integrated value obtained by integrating a speed deviation between a speed command for the mover and an actual speed of the mover, and performs first digital filter computation on the current command value. The control device calculates a current command value for the stator based on a second speed integrated value obtained by integrating a speed deviation between a speed command for the mover and the mover's actual speed, and performs second digital filter computation on the current command value. The current command calculating unit calculates a second speed integrated value based on the first speed integrated value used by the control device, and performs the second digital filter computation using a value of the first digital filter computation of the control device.
