Embodiment Construction

[0026] Such as figure 1 , 2 As shown, in view of the shortcomings of the prior art, the present invention proposes an autonomous diagnosis method for formation configuration control strategy, which can diagnose the whole process from control strategy to control command according to the characteristics of formation control, ensuring the correct and effective implementation of autonomous formation control . The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0027] In order to achieve the above objective, the present invention is achieved through the following technical solutions:

[0028] Step 1 Before calculating the formation control strategy of the satellite, check the status related to the strategy: check that the measurement sensor, the on-board computer, and the formation thruster are all working normally, and the relative / absolute navigation is in a stable state, then the control speed increment is generated Sequence Δv i ....

Abstract

The invention relates to an autonomous diagnosis method for a formation configuration control strategy, and the method comprises the specific steps: step 1, carrying out state inspection related to astrategy before a satellite calculates the formation control strategy; step 2, enabling the satellite to carry out correctness autonomous diagnosis on the control strategy delta vi according to the current formation configuration parameter; if the diagnosis is passed, entering the next step; otherwise, setting an alarm mark; step 3, after the control speed increment sequence delta vi passes the diagnosis, converting delta vi into a control instruction sequence (Tpi, Lti) according to the current on-board time, the actual thrust of the thruster and the satellite mass, and carrying out autonomous diagnosis on the correctness of a control instruction; if the diagnosis is passed, executing the instruction; otherwise, setting an alarm mark.

Description

Technical field [0001] The invention relates to the technical field of satellite high-precision formation / orbit control, in particular to an autonomous diagnosis method of formation configuration control strategy. Background technique [0002] With the continuous expansion of the application range of formation satellites in orbit, complex applications have placed higher demands on the control accuracy and autonomy of formation satellites. In particular, high formation control accuracy requires high control frequency to ensure that the control methods that used to rely on the ground are becoming less and less adaptable to new developments, which further stimulates the urgency of autonomous formation control. The prerequisite for the autonomy of formation control is the correctness of the control commands, so the autodiagnosis of the formation configuration control strategy is a necessary element to ensure the autonomy of formation control. The existing research results of formati...
