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

MATLAB Note

It is fine to model this sensor as a transfer function. However, when combined into a larger LTI model it is recommended that every individual piece of the larger model be converted to a state-space object. State-space objects are more accurate.

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