Abstract
Because rotorcraft is unstable, it needs a stability system such as flybar. Recently, sensor technology has been developed, it uses a stability augmentation system to improve stability instead of flybar. To use of these rotorcraft which include stability augmentations system for unmanned system, flight control computer, include stability augmentations system function, must be required. In this paper, a reverse-engineering method of estimating Algorithm of Commercial Stability Augmentation System is proposed, the result is applied in the flight computer to make an unmanned rotorcraft system. Finally using a validated algorithm, it is possible to establish a system of unmanned automatic rotorcraft system.
