Research of motion resolving and filtering algorithm of a ship's three-freedom motion simulation platform based on LabVIEW

A method to measure, resolve and filter the attitude of the three-freedom simulation platform is presented in this paper. The strapdown measurement system is composed of three single-axis angular speed gyros and three acceleration transducers. Kalman filtering algorithm and self-adaptive Kalman filtering algorithm are adopted to filter the signal. The strapdown measurement system's signal measurement, resolving and filtering are realized through LabVIEW, and the result shows that the measurement, resolving and filtering of the attitude are correctly done using this method, providing correct platform motion attitude signal.
