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...
