Kurzfassung englisch:
Accurate modeling of MOEMS mirrors is crucial for their design and fabrication, as well as for proper control within its target applications. This paper proposes a novel identification method using a generalized nonlinear SDOF model of an electrostatically actuated 1D resonant MOEMS mirror solely based on measured scanning trajectories and the current generated by the movement of the comb-drive electrodes. The nonlinear stiffness and damping are identified from a decay measurement while the comb-drive torque and the rotor inertia are derived from an actuated decay measurement, where a constant voltage is applied. The simulation with the identified parameters closely matches the measured frequency response including bifurcations and hysteresis. Furthermore a period-based modified index of agreement is proposed for nonlinear systems showing values of over 0.995 at each period along the decay.
