Abstract

The invention discloses a longitudinally controlled flight energy management method, system, electronic equipment and computer-readable storage medium of an unpowered aircraft. The method includes the following steps: calculating the dynamic guide amount, calculating the normal guide amount of the longitudinal velocity, Calculate the normal guidance amount in the stable stage, and calculate the longitudinal guidance command of the aircraft. The present invention estimates the current energy of the aircraft by using the current state of the aircraft and the remaining range, designs the control strategy, and obtains the longitudinal guidance command of the aircraft. During the entire calculation process, it does not involve solving the extreme value, so it will not fall into the optimal solution, and can Effectively converge the energy of the aircraft. The calculation process of this method is relatively simple and easy to implement.

Description

technical field

[0001] The invention relates to the technical field of aircraft flight control, in particular to a method and system for energy management of longitudinally controlled flight of an unpowered aircraft. Background technique

[0002] For unpowered aircraft, especially for long-duration and long-distance flight missions, the energy deviation caused by the deviation of aerodynamic parameters and atmospheric density will increase over time, eventually leading to excessive energy dispersion at the end, and even causing the trajectory to diverge during the flight, which is not conducive to Later task handover. The purpose of energy management is to control energy accumulation deviation and prevent track divergence. The energy of an unpowered aircraft is designed according to its maximum range, and for general tasks, there will be a certain amount of energy left. The energy management control maneuver is mainly to calculate the excess energy by continuously predicti...
