ABSTRACT
The UAV is considered as a single rigid-body, for a certain UAV system, the following are defined for the longitudinal model:
x q h y V q h u

Δ Δ Δ Δ Δ
α Δ
δ (1)
where V, α, q, θ, δe are the airspeed, angle-of-attack, pitch rate, pitch angle, altitude and elevator deflection respectively. Similarly, for the lateral model,

Δ Δ Δ Δ Δ
β φp, ,Δ Δ Δr φ
δ δΔ, (2)
where β, p, r, φ, δa, δr are the sideslip angle, roll rate, yaw rate, bank angle, aileron deflection and ruder deflection respectively.
