The image above represents transfer function (sensitivity). To calculate transfer function (sensitivity) | Second Order Instrument, five essential parameters are needed and these parameters are Static Sensitivity (k), Dumping Ratio (ε), Undefined Natural Frequency (ωo), Differentiation Value (d / dt) (D) and Differentiation Value (d2 / dt2) (D2).
The formula for calculating transfer function (sensitivity):
c = k / 1 + 2εD / ωo + D2 / ωo2
Where:
c = Sensitivity
k = Static Sensitivity
ε = Dumping Ratio
ωo = Undefined Natural Frequency
D = Differential Value
D2Â = Differential Value
Let’s solve an example;
Find the transfer function when the static sensitivity is 8, the dumping ratio is 12, the undefined natural frequency is 10, the differential value is 7 and the differential value is 3.
This implies that;
k = Static Sensitivity = 8
ε = Dumping Ratio = 12
ωo = Undefined Natural Frequency = 10
D = Differential Value = 7
D2 = Differential Value = 3
c = k / 1 + 2εD / ωo + D2 / ωo2
Then, c = 8Â /Â 1 +Â 2 x 12 x 7Â /Â 10Â +Â 3Â /Â 102
c =Â 8Â /Â 1 +Â 168Â /Â 10Â +Â 3Â /Â 100
c =Â 8Â /Â 1 + 16.8 + 0.03
So, c = 8Â /Â 17.830
c = 0.448
Therefore, the transfer function (sensitivity) is 0.448.
