The hysteresis compensation method is studied.A control system is established based on Jiles-Atherton hysteresis model and its main parameters are introduced. Then

according to Jiles-Atherton hysteresis model

the variation relation between magnetization and field intensity is analyzed. Finally

based on above analysis

a hysteresis compensation method using the width of hysteresis ring to recalculate the initial value for recursive algorithm at turning point is proposed. The experiment results indicate that

comparing with a actuator without hysteresis compensation

there is no time delay in proposed system and the settled time is 12 ms reduced for step response

Also

there is no time delay and the MSE is 0.19 μm improved for sine wave tracking

which shows that the compensation method can overcome the hysteresis effect and improve positioning precision effectively.
