| Popis: | This paper focuses on stability augmentation control system development for fixed-wing Turbojet Unmanned Aerial Vehicle (UAV). UAV model is generated by using digital DATCOM software to calculate aerodynamic derivatives. Longitudinal flight dynamics will be used to synthesize control responses in xb and zb plane. This research of stability augmentation uses Linear Quadratic Regulator (LQR) approach. Flight stability of this UAV comes from a solution to Differential Riccati Equation (DRE) which provides optimal controller gain to adjust the states. The simulation results depict that the proposed method can be considered to improve flight performance in the presence of disturbances. |
