Longitudinal control flight energy management method and system for unpowered aircraft

Abstract

The invention discloses a longitudinal control flight energy management method and a longitudinal control flight energy management system for an unpowered aircraft, electronic equipment and a computer readable storage medium. The longitudinal control flight energy management method comprises the steps of calculating a dynamic guidance quantity, calculating a normal guidance quantity of a longitudinal speed, calculating a normal guidance quantity in a steady phase and calculating a longitudinal guidance command of the aircraft. The longitudinal control flight energy management method and the longitudinal control flight energy management system utilize the current attitude and the range-to-go of the aircraft to estimate current energy of the aircraft, design a control strategy, calculate the longitudinal guidance command of the aircraft, cannot be trapped in solving an optimal solution since the solution of an extremum is not involved in the whole calculation process and can effectively converge energy of the aircraft. The longitudinal control flight energy management method has relatively simple calculation process, and is easy to implement.

Description

Technical field [0001] The invention relates to the technical field of aircraft flight control, in particular to a longitudinal control flight energy management method and system for an unpowered aircraft. Background technique [0002] For unpowered aircraft, especially for long-duration and long-distance missions, the energy deviation caused by aerodynamic parameters and atmospheric density deviations will accumulate and increase over time, eventually leading to excessive end energy spread, and even causing track divergence during flight, which is not conducive to Later task handover. The purpose of energy management is to control the deviation of energy accumulation and prevent divergence of the track. The energy of an unpowered aircraft is designed according to its maximum range. For general tasks, there will be a certain amount of energy remaining. Energy management control maneuver is mainly to calculate excess energy by continuously predicting the flight trajectory during...

AI Technical Summary

Problems solved by technology

Aircraft usually achieve energy management by adjusting the height of the flight path or in-plane maneuvering, such as the closed-circuit guidance method. When this method performs energy management, the calculation process is more complicated, and it may obtain a local optimal solution instead of an overall optimal solution, resulting in inability to Converging Aircraft Energy
