Abstract

The invention provides a dual-super-satellite platform load cabin compound control method. The method includes the following steps that firstly, the attitude of a load cabin is controlled; secondly, the attitude of a platform cabin is controlled; thirdly, the relative positions of the platform cabin and the load cabin are adjusted; and fourthly, according to attitude information of the load cabin,the attitude control system bandwidth of the load cabin is adjusted, and the attitude of the load cabin is restrained. The method has the beneficial effects that through dual-super-platform master and slave cooperative control, load cabin interference compensation control and a variable bandwidth control method, the steady state time of the load cabin is prolonged, and the steady state accuracy of the load cabin is improved.

Description

technical field [0001] The invention relates to a compound control method for a satellite platform load compartment with ultra-high pointing accuracy and ultra-high stability (double super), the platform adopts the active control of the load compartment, the slave control of the platform compartment, and the control method of coordinated decoupling of the two compartments . When the two cabins are initially unlocked in orbit, in order to overcome the impact interference of unlocking, the load cabin adopts high-bandwidth control to make its attitude converge rapidly. control. The load compartment adopts a composite control method, which can improve the attitude stabilization time and stabilization accuracy, and meet the needs of high-precision ground remote sensing. Background technique [0002] The requirements for attitude pointing accuracy and stability of advanced spacecraft in the future are two orders of magnitude higher than the current level, and the dual supersessi...
