摘要

Control input histories are determined for flying precision three dimensional aerobatic maneuvers using inverse-control and optimization methods. A mass point model is used with three controls, angle-of-attack, bank angle, and thrust. Bounds are placed on normal load factor, thrust, and angle-of-attack. By choosing cylindrical coordinates for the position vector and spherical coordinates for the velocity vector, simple inverse solutions are found for standard aerobatic maneuvers. Requiring constant radius and constant helix angle produces nonlinear feedback laws for angle-of-attack and bank angle. Numerical results are presented for an F4H aircraft performing barrel rolls.
