Adaptive Control of Magnetic Drive Actuator for Laser Cutting
This paper describes an adaptive control method for a magnetic drive actuator that used for the laser cutting to realize high speed and high accuracy machining.Firstly,a zero bias current method and a nonlinear compensator are examined and used for the actuator.Secondly,an adative control method is presented.Finally,the coefficient of the gap-current-force is estimated and the effectiveness of the presented control method is verified by experiments.The experimental results show that the coefficient of the gap-current-force reduces exponentially depending on the increase in the length of the air gap.By using the adaptive control,the peak-to-peak vibration amplitude of the lens holder is reduced from 1.95μm to 1.55μm.
