Abstract
This paper had studied on the zero temperature compensation of fluidic gyroscope based on MEMS thermistor. Through the analysis of temperature characteristics of jet gyro sensitive element, two methods of comparison of zero temperature compensation was compared. Then, introduction of SCM and temperature sensor, to achieve zero temperature compensation for gyro output signal. The experiment shows: after compensation, zero voltage variation gyro reduced from 150mV to 10mV, working temperature range from room temperature to-40°C ~+55 °C. The fluidic gyroscope zero temperature compensated with zero drift is low, wide working temperature range advantages.
