CTM Example: Modeling Pitch Controller: Variables

Example: Pitch Controller--Variables

Here are the variables used in the pitch controller modeling equations

= Angle of attack

= Pitch rate

= Pitch angle

= Elevator deflection angle

= Density of the surrounding air

= Planform area of the wing

= Average chord length

= Mass of the aircraft

U = Equilibrium flight speed

= Coefficient of thrust

= Coefficient of drag

= Coefficient of lift

= Coefficient of weight

= Coefficient of pitch moment

= Flight path angle

= Constant sigma

= Normalized moment of inertia

= Constante nu
