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...

Abstract: The main vibration of interior permanent magnet synchronous motor(IPMSM)with integer slot multipole pair for electric vehicles is the vibration at 0-order and 2p-order natural frequencies, which are generally believed to be caused by the spatial electromagnetic force waves of 0-order and 2p-order. In order...
