## 2 Honeywell GG5300 MEMS Rate Gyro

Honeywell GG5300 MEMS Rate Gyro Plant

The Honeywell GG5300 Three Axis MEMS Rate Gyro is advertised as being for "Missiles & Munitions." The datasheet available on Honeywell's website states

 Bandwidth @ 90 deg phase 100 Hz typical

The typical sensor model would have the following parameters

 $LaTeX: \omega_n=100$ Hz, $LaTeX: \zeta=\frac{1}{\sqrt{2}}$, $LaTeX: K=1$

The sensor has a scale factor (Volts per radian) that we are ignoring for now. (The scale factor here is just a gain. External electronics can make this scale factor whatever is convenient.) Using the parameters in the above table a transfer function can be formed in MATLAB with the following commands

 >> wn = 100 * (2*pi);
>> z = 1/sqrt(2);
>> K = 1;
>> GG5300 = tf(K * [wn^2], [1, 2*z*wn, wn^2]);


The resulting frequency response for a single axis is

For most models each axis can be modelled with an identical transfer function.
