Implementation of extended high-gain observer in low-cost optitrack motion tracking system for UAV control
The objective of this paper is to present the implementation procedure and experimental results of using Extended High-Gain Observer (EHGO) in estimating the states from low-cost Optitrack camera that is being used as the motion tracking in the Unmanned Aaerial Vehicle (UAV) system. Owing to the low...
