Abstract
We have demonstrated a closed-loop feedback-control system that dramatically improves the dynamic response, settling time, and external disturbance rejection of a magnetic micromirror. Proportional, proportional-derivative and proportional-derivative-integral controllers (implemented on a digital signal processor) were used to increase positioning accuracy of the micromirror which can, for example, lead to increased optical-channel density in fiber-optic switches.
