[Autopilot] Linearity of ENC-03J gyroscope

[bingwei s. <bs...@en...>]

hello,


In there data sheet, "Linearity" was definated as "Deviation of output from
the ideal straight line
defined by scale factor. Linearity of clockwise obeys the follozwing
equation"


                  Sv_omega - Svmax * omega/omega_max
Linearity =--------------------------------------------- * 100( %)
                                       Svmax


omega :       angular velocity
omega_90:  omega_90 = + 90deg/s  ( seems they forgot use this in the
equation)
Sv_omega:  scale factor at angular velocity is omega (deg/s)
Sv:              scale factor at angular velocity is omega_90(deg/s)

(they didn't give the defination of Svmax, maybe the maximum value of scale
factor related to
different input voltage.)

and the tipical number of Linearity they gave is 5.

I think if the sensor is perfect, the Linearity should be 0 by the
defination, then the equation
above equals zero, which means

Sv_omega = Svmax * omega/omega_max

But by physical concept, if the sensor is perfect, then I think: Sv_omega =
Svmax. I was confused by the
defination above.

Can you give me some advice? Thank you in advance.
