The effect of automatic flight control system structure on attenuation of the short-period aircraft vibrations due to atmosphere turbulence

Jerzy Borowski, Wiesław Sobieraj
The influence of selected control laws representing autopilot structures on attenuation of the short-period vibrations due to atmosphere turbulence has been examined in the paper. A nonlinear model of the aircraft dynamics and a turbulence model representing stochastic enviromental conditions have been applied to computer simulation of the problem. Numerical calculations were made for three selscted control laws for their applicability to the 1-22 Iryda automatic flight control system to be assessed.
