UAV program motion and control in prescribed mission

Wojciech Blajer, Jerzy Graffstein, Mariusz Krawczyk
The paper deals with the inverse simulation problem of aircraft general motion. The aircraft is constrained to follow a specified 3D trajectory (two program constraints), and two other demands, are imposed on airframe attitude with respect to the trajectory and on flying speed. The guidelines for effective modelling of aircraft prescribed trajectory flight are discussed, and a method for computing time histories of state variables and program control (that ensures the programmed motion realization) is developed. Some results of numerical simulations are reported.
