The Dynamics of a Linear Second Order System
The solution of the linearised small perturbation equations of motion of an aircraft
contains recognisable classical second order system terms. A review of the dynamics
of a second order system is therefore useful as an aid to the correct interpretation of
the solution of the aircraft equations of motion.
Consider the classical mass–spring–damper system whose motion is described by
the equation of motion
m¨x(t) +c˙x(t) +kx(t) = f (t) (A6.1)
where x(t) is the displacement of the mass and f (t) is the forcing function. The
constants of the system comprise the ...
