Robust Current Control of Voice Coil Motor in Tip-Tilt Mirror Based on Disturbance Observer Framework
In this paper, a control methodology based on the disturbance observer (DOB) framework is proposed to improve the current dynamic characteristic and the robustness of the voice coil motor (VCM) in the tip-tilt mirror. It is shown that the open-loop current characteristic is a third-order plant, whic...
