Abstract

The invention relates to a neural network based double-super-satellite payload bay interference compensating method, and belongs to the technical field of space satellites. The method comprises the following steps: 1, analyzing interference of a double-super-satellite payload bay; and building an interference type mathematic model of the payload bay; 2, performing neural network parameter trainingon the basis of the neural network based interference type mathematic model so as to obtain estimation value of interference; and 3, designing a posture compensating control law based on the estimation value of interference; and compensating the interference to realize high-accuracy control performance of the payload bay. According to the method, the uncertain interference of a double super satellite can be compensated; the interference handling capacity is extremely improved; and the super accuracy and super stability of the satellite can be ensured.

Description

technical field [0001] The invention relates to the technical field of aerospace satellites, in particular to a neural network-based interference compensation method for double supersatellite load cabins. Background technique [0002] Satellite platform (satellite platform) is composed of satellite service (guarantee) system, which can support one or a combination of several payloads. The satellite platform is actually the rest of the satellite except for the payload or payload bay. The satellite platform can be combined into one or several compartments by the satellite service (guarantee) system, such as service compartment, propulsion compartment and return compartment. [0003] From the analysis of successfully developed satellites, no matter what payload is installed on the satellite platform, its basic functions are the same, but the specific technical performance will be different. According to this feature, many countries in the world have adopted the design idea of...
