Embodiment Construction

[0041]The invention discloses a design method of a multi-component dynamics simulation module of an attitude-orbit control system. The method adopts the idea of ​​splitting and refining the dynamics simulation module, instead of placing the running time domain of the dynamics simulation module at a fixed position in the control cycle, but splitting the dynamics simulation module into several sub-modules , according to the actual performance requirements to determine the degree of refinement, each sub-module rearranges the execution time domain according to its execution sequence and time margin requirements, and sets the call flag for each component, and only outputs data in the cycle that needs to be called, as much as possible Optimize and balance simulation performance. On the premise of not losing the degree of system simulation, it successfully solved the time bottleneck problem of multi-component dynamic simulation, and has been successfully used in the space station sim...

Abstract

The invention discloses a design method of a multi-component dynamics simulation module of an attitude and orbit control system. A pin thinking that a dynamics simulation module disperses and refinesis adopted. The operation time domain of the dynamics simulation module is no longer placed at a fixed position of the control period in a unified manner; instead, the dynamics simulation module is split into a plurality of sub-modules, the refinement degree is determined according to the actual performance requirement, each sub-module rearranges the execution time domain according to the execution sequence and time margin requirement of the sub-module, a calling mark is set for each part, data output is conducted only in the period needing to be called, and the simulation performance is optimized and balanced as much as possible. On the premise that the simulation degree of the system is not lost, the time bottleneck problem of multi-component dynamics simulation is successfully solved. The method is successfully applied to a space station simulation environment at present.

Description

technical field [0001] The invention relates to a design method for a multi-component dynamics simulation module of an attitude-orbit control system, which belongs to the field of simulation of an aerospace attitude-orbit control system. Background technique [0002] The spaceborne attitude and orbit control system completes the following tasks sequentially in each cycle: data acquisition (45ms), GNC (Guidance Navigation and Control) (100ms), data output (25ms), system management (30ms). The tasks that the corresponding dynamic simulation system needs to complete include: receiving the data output by the spaceborne attitude and orbit control system in the data output task, transmitting the data to the dynamic model for dynamic calculation, and returning the calculation results to the spaceborne attitude and orbit The control system is acquired by the spaceborne attitude and orbit control system in the data acquisition task to form a closed-loop simulation. The commonly used...
