This paper presents the nonlinear six degrees of freedom dynamic modeling of a fixed wing micro air vehicle.The static derivatives of the micro air vehicle are obtained through the wind tunnel testing.The propeller effects on the lift, M Shorts drag, pitching moment and side force are quantified through wind tunnel testing.The dynamic derivatives are obtained through empirical relations available in the literature.

The trim conditions are computed for a straight and constant altitude flight condition.The linearized longitudinal and lateral state space models are obtained about trim conditions.The Decanters variations in short period mode, phugoid mode, Dutch roll mode, roll subsidence mode and spiral mode with respect to different trim operating conditions is presented.A stabilizing static output feedback controller is designed using the obtained model.

Successful closed loop flight trials are conducted with the static output feedback controller.
