Js. Brinker et Ka. Wise, STABILITY AND FLYING QUALITIES ROBUSTNESS OF A DYNAMIC INVERSION AIRCRAFT CONTROL LAW, Journal of guidance, control, and dynamics, 19(6), 1996, pp. 1270-1277
Dynamic inversion, or feedback linearization theory, represents a comm
only used nonlinear control method for designing aircraft control laws
. This method has the ability to control a highly nonlinear plant but
suffers from the lack of guaranteed robustness. The stability and flyi
ng qualities robustness of a dynamic inversion based control law, desi
gned for a prototype aircraft, to uncertain aerodynamic parameters is
analyzed. The results indicate that the pitch plane stability and dyin
g qualities are robust to parameter uncertainties, but the lateral dir
ectional dying qualities are sensitive to uncertain stability derivati
ves.
