Abstract: In the galvanometer scanner system，the motor should meet the requirement of 2°/200 Hz highfrequency response. It was inappropriate to utilize PID controller under the demands of small-inertia，lowamplitude，high-frequency. Therefore，many control algorithms are studied and applied，such as currentmultisampling...
