Abstract :
This paper first provides the design scheme of sensors data acquisition system which mainly includes two parts: the data acquisition based on DSC (digital signal controller) and the data processing based on LabWindows/CVI. The drift error data are measured through this test. Then the drift characteristics ARMA model is identified. Based on this model, the corresponding robust filter is designed by means of the LMI-based robust filter method proposed in this paper. Compared it with the Kalman filter through simulation, the proposed method has improved the estimation accuracy of the gyro drift and guaranteed the validity of error compensation.
