Abstract

The invention discloses a method for unbiased flight control of a satellite's nominal orbit, comprising: establishing the motion equation of the relative mass block of the satellite; constructing a nonlinear predictive control model according to the motion equation; and rolling optimization according to the nonlinear predictive control model Calculate the optimal thrust control amount of the satellite; according to the optimal thrust control amount, make the satellite fly along the nominal orbit without deviation. The method provided by the invention improves the technical problem of insufficient accuracy existing in the unbiased flight control of the nominal orbit of the existing satellite. The accuracy of the unbiased flight control of the existing satellite's nominal orbit is effectively improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for unbiased flight control of a satellite's nominal orbit. Background technique [0002] Facing the future, a large number of cutting-edge disruptive applications such as high-precision military remote sensing, high-precision navigation, and electromagnetic space reconstruction have put forward unprecedented demands on the high-precision and long-term autonomous navigation capabilities of space nodes. According to the existing model, the cost of building a spatial benchmark is huge, and the accuracy is still limited by the bottleneck of dynamic constraints. Therefore, it is necessary to rethink the construction style of high-precision spatial nodes and explore new principles of autonomous navigation. In order to improve the accuracy of the space reference, it is necessary to build an ultra-high-precision space reference station satellite to achieve the highest precis...
