Dynamic System Identification of Unmanned Air Vehicle Octorotor Helicopter

Riyanto Bambang


This paper presents a method for the dynamic system identification and simulation model development of Octorotor Helicopter UAV. A complete dynamic model was derived for both hover condition. In addition to standard Octorotor Helicopter flight characteristic, the model explicitly accounts for the stabilizer bar, which has a strong influence on the flight dynamics and is widely used in model-scale Octorotor Helicopter. The accuracy of the developed model is verified by the comparison between predicted and actual responses from the model and the flight experiments (in both frecuency and time domains), and between key identified parameters and their theoretical values. Scaling of the main characteristics of the Octorotor Helicopter with respect to those of performed to determine how the size influences the flight dynamics of Octorotor Helicopter.
