Ag. Sreenatha et Sk. Nayak, Analysis of the steady state effects of the control surface nonlinearitiesan the performance of a fighter aircraft, J VIB CONTR, 6(6), 2000, pp. 923-935
The nonlinearities present in the control surface of an aircraft can alter
both the stability and performance characteristics. The typical nonlinearit
ies generally considered are the "saturation" and the "dead band." The pres
ent work shows that these can lead to loss of steady-state accuracy. A simp
le formulation in terms of the eigenvalue problem is presented to predict t
he steady-state behavior. Analytical and numerical results for a fighter ai
rcraft model are presented to demonstrate the utility of the methodology de
veloped.
