Study on Fluidic Gyroscope Linearity Compensation Method

Abstract:

Based on the linearity of the MEMS thermal element fluidic gyroscope compensation. By analyzing the results of the linear characteristic of the fluidic gyroscope sensor output, comparator linearity compensation two implementation methods, the introduction of the microcontroller and the temperature sensor, to achieve the linearity compensation of the gyro output signal. The experiments show that: after compensation, the non-linearity of the fluidic gyroscope5%down to 0.5%, to-120°/s~+120°/s measurement range from-40°/s~+40°/s Fluidic gyroscope linearity compensation with low non-linearity, wide measuring range.
