System identification, estimation and control for a cost effective open-source quadcopter
Sa, Inkyu & Corke, Peter (2012) System identification, estimation and control for a cost effective open-source quadcopter. In Papanikolopoulos, Nikos (Ed.) Proceedings of the 2012 IEEE International Conference on Robotics and Automation, IEEE, River Center, Saint Paul, Minnesota, pp. 2202-2209.
This paper describes system identification, estimation and control of translational motion and heading angle for a cost effective open-source quadcopter — the MikroKopter. The dynamics of its built-in sensors, roll and pitch attitude controller, and system latencies are determined and used to design a computationally inexpensive multi-rate velocity estimator that fuses data from the built-in inertial sensors and a low-rate onboard laser range finder. Control is performed using a nested loop structure that is also computationally inexpensive and incorporates different sensors. Experimental results for the estimator and closed-loop positioning are presented and compared with ground truth from a motion capture system.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
