ボイスコイルモータの力制御とシャント制振を同時に実現する２自由度制御器設計

抄録

In general, PI feedback control is used for actuation by the voice coil motor. However, if the mechanical system is subjected to disturbance, the vibration of the system is not significantly suppressed. One of vibration damping methods using a voice coil motor is electromagnetic shunt damping, which can suppress the vibration only by attaching the shunt circuit to the voice coil motor. In this paper, we propose the two-degrees-of-freedom control which simultaneously performs force control and electromagnetic shunt damping.
