Summary:
In this study, a control strategy is applied to a Digital Micromirror Device (DMD) to maneuver its angular motion. The micromirror is actuated using an electrostatic field. The equations of motion of the system are derived using the Extended Hamilton’s Principle. The static response of the DMD for different DC loads (bias and address voltages) is analyzed. The linear vibration behavior of the DMD is examined by plotting the natural frequencies versus the considered DC voltages. The proposed control strategy is done by the Bang-Bang technique which is suitable in optimal control problems where the control switches from one extreme to the other at certain time instants. This control strategy allowed decreasing the residual vibration of the micromirror when it switches from a position to another and then reduced its resultant switching time.
