    In this presentation, five contents will be include,

    1.  Algorithms introduction of a ring vibrating MEMs gyroscope: Vibration modes,

    2.  Dynamic model,

    3.  Parametric excitation of the primary mode:

    4.  Parametric amplification of the coriolis force:

    a.  Difficulties in phase control to amplify the coriolis force

    b.  Electrostatic tuning: mode angle, mode coupling, frequency split.

    c.  Open loop control scheme and results

    5.  DSP implementation:

    a.  Structure of DSP based Gyroscope control system

    b.  Major issues in the implementation: signal generation, measurements, synchronous demodulation, real time programming and etc.
