Abstract
Control method and control apparatus are capable of preventing vibrations of the feed system and thereby maintaining its optimum operating state for a long run. The control apparatus (1) includes an operation command generator (3) for generating an operation command signal according to an NC program, a position controller (4) for generating a speed command signal by multiplying a deviation between an operation command signal and a current position signal by a positional loop gain, a speed controller (5) for generating an electric-current command signal by multiplying a deviation between a speed command signal and a current speed signal by a speed loop gain, a filtering processor (6) for eliminating frequency components of a predetermined frequency band from the electric-current command signal, and adjusting processor (20) for adjustment of the elimination frequency band in response to the detected vibration level and vibrational frequency.
