Abstract

A carrier energy management section FADS failure judgment and control method, comprising the following steps: obtaining atmospheric data measurement data and inertial measurement data under wind interference; analyzing the characteristic difference between the atmospheric data measurement data and the inertial measurement data; Establish the mathematical representation of the safety boundary of the air data measurement data according to the distribution law of profile height, speed, heading, wind speed and wind direction; judge whether the atmospheric measurement information is in the safety boundary according to the coverage degree of the air data measurement data safety boundary to the atmospheric measurement data Range, when the atmospheric measurement information is not within the safe boundary range, it is judged that the air data sensing system is faulty; when the air data sensing system is faulty, the longitudinal control is performed according to the critical state boundary protection or the roll control is performed according to the sideslip angle boundary protection. In the case of FADS failure or no atmospheric data measurement information during the unpowered return process, the vehicle can still be safely and reliably controlled, ensuring the safe landing of the spacecraft.

Description

technical field [0001] The application belongs to the field of aerospace technology, and in particular, relates to a vehicle energy management section FADS fault judgment and control method, a vehicle and a storage medium. Background technique [0002] The technical level of the space transportation system represents a country's ability to independently enter and exit space, reflects a country's ability to use space and develop space technology, maintains a country's space security and space interests, and is also a symbol of comprehensive national strength. With the rapid development of the field of space transportation in recent years, the concept of "reuse" has been paid more and more attention. The reusable vehicle is an ideal transportation tool to reduce the cost of space transportation, improve safety and reliability, and shorten the preparation time for transition. It is an important part of my country's space transportation system in the future. In addition, from t...
