Xuan Fang, Bocheng Zhong, Xingtao Ding . An Analysis System for Attitude Angles of Four-rotor Aircrafts. International Journal of Computer Applications. 149, 3 ( Sep 2016), 41-45. DOI=10.5120/ijca2016911375
Abstract
More accurate attitude angles can make the control of four-rotor aircrafts more precise. Various filters have been adopted to get more precise attitude angles. However, so far there is no suitable analysis system to evaluate the performance of filters. In this paper, an analysis system has been designed which can get the realistic attitude angles directly and compare the processing results of filters so as to analyze the performance of filters. The hardware of the analysis system contains the main control module, data acquisition module and wireless communication module. And the software of the system which is designed by LabVIEW mainly includes displaying and saving module, analysis module and the front panel. An extended Kalman filter and an innovation-based extended Kalman filter are compared by the system and results show that the attitude angles got by the innovation-based extended Kalman filter are more accurate than the extended Kalman filter.
