摘要：
The software compensation technology of the piezoelectric fluidic gyroscope based on DSP digital processing is designed in the paper. Using the DSP, the zero-temperature compensation, sensitivity-temperature compensation and nonlinearity compensation could be solved by combining method with the data interpolation and the second table look-up. The experiment results are as follow: after the software compensation, the zero-temperature drift declines from <= 1.5mV/degrees C to <= 0.2 mV/degrees C, the sensitivity coefficient declines from <= 2mV/degrees/s/degrees C to <= 0.2mV/degrees/s/degrees C, the nonlinearity declines from <= 5% to <= 1.2%, in the measurement range of -60 degrees/s similar to+ 60 degrees/s, working temperature range is extended to -40 degrees C similar to+ 60 degrees C. such compensation technology, simple. It has practical value to improve the performance of fluidic Gyroscope temperature and linearity, expand the field of the use of fluidic Gyroscope.
