Research on Nozzle Array Structure Fluidic Gyroscope Signal Compensation Circuit

Abstract:

The nozzle array structure fluidic gyroscope signal compensation circuit was researched. To compensate output voltage signal from the first stage of the gyroscope angular rate sensitive element, which had the perfect linearity and operating temperature range, the signal compensation circuit was designed. Then, the circuit function and principle for each module was analyzed. The signal compensation circuit is composed up Single chip microcomputer, temperature sensor, voltage regulator circuit and peripheral circuit. The experiment results shows that using the signal compensation circuit, the fluidic gyroscope linearity is 1% and operating temperature range is -60°C~+60°C. Therefore, the signal compensation circuit realizes the voltage signal temperature compensation and eliminates noise jamming from the external environment, which provides the foundation for the fluidic gyroscope production and application.
