In order to model the Fuzzy controller for Coriolis meter first
the Input Linguistic variable should be identified. The Input
linguistic variables for Coriolis flow meter are considered as
bellow:
Damping
In Coriolis flow meter, tubes are maintained to oscillate by
using a positive feedback. As result of the feedback, driver
supplied current is provided by consideration of the drive gain
and sensor signal. Sensor signal indicates phase and
frequency of flow tube oscillation that is related dampening.
Damping can be modelled in the following manner
