Integration inverse method for real-time simulation and control of flight vehicles

摘要

An inverse dynamic approach for real-time simulation and control is proposed. This technique is especially useful if the flight vehicle has onboard computer. The method consists in adding to the forward integration a pre-process of solving a system of nonlinear algebraic equations representing outputs, one for each active control. This system is constituted by following some association rules, fully discussed. Output equations respecting these rules define a maneuver in a special way called evolution prototype. This formulation is essential for computational speed performance, enabling real-time guidance and control based on the complete nonlinear dynamics of the vehicle. A group of significant prototypes for lateral and longitudinal maneuvers is presented, the development of new ones being unlimited. Real-time simulations for climb and roll on a subsonic training aircraft illustrate precision of the algorithm and the efficiency of proposed prototypes.
