Abstract
The nozzle array structure fluidic gyroscope’s zero temperature compensation was researched. The fluidic gyroscope’s temperature characteristic was analyzed in the sensitive element and two zero temperature compensation methods were compared. Then, the software compensation method was used, which based on the Single chip microcomputer technology and realized temperature compensation for the gyroscope output signal. The results show that after the compensation, the gyroscope’s zero drift decreases from ≤1.3mV/°C to ≤0.1mV/°C and operating temperature range increases from normal temperature to -40°C~+60°C. Therefore, the fluidic gyroscope has the advantage of low zero drift and width operating temperature range after the zero temperature compensation, which provides the convenience for the production and application.
