Abstract

The invention relates to the technical field of spacecraft control, and discloses a method for constructing a polarity fault mode recognition model of an attitude control system, and the method comprises the steps: obtaining a plurality of training samples and sample labels corresponding to the training samples; each training sample comprises sample attitude control parameter data; and inputting the training sample with the sample label into a preset neural network for training to obtain a polarity fault mode recognition model of the attitude control system. And various polarity fault modes of the attitude control system can be identified through the polarity fault mode identification model of the attitude control system. The invention further discloses a device for constructing the polarity fault mode recognition model of the attitude control system, electronic equipment, a storage medium, a method and device for recognizing the polarity fault mode of the attitude control system, the electronic equipment and the storage medium.

Description

technical field [0001] The present application relates to the technical field of spacecraft control, and in particular, relates to a method for constructing a polar failure mode recognition model of an attitude control system. Background technique [0002] In the space launch, although both the launch vehicle and the satellite have been fully tested before the flight, failures caused by wrong polarity occur from time to time. The polarity error of the attitude control system of the launch vehicle will cause the attitude control parameters to diverge rapidly, which will have a great impact on flight stability and control accuracy. Therefore, there is an urgent need for a technology that can identify the polar fault mode of the attitude control system. Contents of the invention [0003] An embodiment of the present application provides a method for constructing a polarity failure mode recognition model of an attitude control system, so as to provide a model capable of recog...
