Abstract
The invention discloses an FADS fault judgment and control method for an energy management section of a vehicle. The method comprises the steps of acquiring atmospheric data measurement data and inertial measurement data under wind interference; analyzing a characteristic difference between the atmospheric data measurement data and the inertial measurement data; establishing mathematical representation of the safety boundary of the atmospheric data measurement data according to the distribution rule of the flight profile height, speed, course, wind speed and wind direction; judging whether theatmospheric measurement information is in a safety boundary range or not according to the coverage degree of the safety boundary of the atmospheric data measurement data on the atmospheric measurement data, and judging that an atmospheric data sensing system breaks down when the atmospheric measurement information is not in the safety boundary range; and when the atmospheric data sensing system breaks down, carrying out longitudinal control according to key state boundary protection or carrying out rolling control according to sideslip angle boundary protection. Under the condition of an FADSfault or no atmospheric data measurement information in the unpowered return process, the carrier can still be safely and reliably controlled, and safe landing of the spacecraft is guaranteed.
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...
