Software Compensation of the Piezoelectric Fluidic Angular Rate Sensor
The software compensation technology of the piezoelectric fluidic angular rate sensor was described. The principle and procedure of the temperature and linearity compensation were provided. Using the microprocessor, the temperature and linearity compensation of sensor could be solved by combining method with the data interpolation and table look-up. The experiment results show that after software compensation, the sensor nonlinearity decreases from 2% to 0.5% and operating temperature range increases from 0°C~45°C to -40°C~55°C. The software compensation method is easy to use and also used for other enough precision sensors.
