Micro-nano satellite attitude and orbit integrated control method of MEMS solid micro thruster

Abstract

The invention discloses a micro-nano satellite attitude and orbit integrated control method of an MEMS solid micro thruster. The method comprises the steps of 1), performing micro-nano satellite relative movement modeling: according to a plurality of micro-nano satellite formation characteristics and earth observation and inter-satellite fault detecting tasks, analyzing an orbit task restraint; 2), performing micro-nano satellite orbit attitude integrated control: according an attitude and orbit integrated control requirement and a micro-nano satellite movement characteristic, performing orbitattitude integrated control by means of a resultant action of the solid micro thruster with a circular topological structure through a satellite mass center direction; 3), establishing a micro-nano satellite thruster dynamical model, and analyzing an igniting sequence optimized model of the micro thruster; and 4), establishing an igniting program of the solid micro thruster, namely according to a0-1 integer programming method, establishing the igniting program of the solid micro thruster. Through designing the igniting combination, a momentum required for attitude and orbit maneuver is supplied for the micro-nano satellite, thereby realizing attitude orbit transfer and satisfying a task requirement.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a micro-nano-satellite attitude-orbit integrated control method of a MEMS solid micro-propeller. Background technique [0002] After entering the 21st century, with the development of aerospace technology, modern satellites gradually show the advantages of light weight, miniaturization, low cost, high functional density and cost performance, and gradually become an important part of space systems. Micro Electro-Mechanical System (MEMS) has great advantages for the development of small satellites, and can be applied to the design of propulsion, communication and other systems. [0003] Compared with traditional satellites, micro-nano satellites have a series of advantages such as small size, light weight, short development cycle, and low research and development costs. Multiple micro-nano-satellites flying together in formation can complete tasks that are difficult for large satellites, ...

Problems solved by technology

Micro-nano-satellites have great application potential. However, due to the relatively small size of micro-nano-satellites, they cannot carry the propulsion system required by conventional satellites, so the maneuverability of satellites will be severely limited.
