Robust controller design for dual-stage actuator against resonant frequency variations in load devices

Robust controller design for dual-stage actuator against resonant frequency variations in load devices

This paper presents a controller design approach for load devices to provide robust properties against variations in resonant frequencies and disturbance forces in the mechanism. In the device, a pneumatic actuator and a voice coil motor are combined as a dual-stage to expand the servo bandwidth of...
