Embodiment Construction

[0025] The specific mathematical models and algorithms used by this thruster array to achieve attitude control and orbit control are given below.

[0026] The schematic diagram of the thruster array is shown in figure 1 shown. The basic generating element of the thruster array is a regular hexagon, which exists in the form of a circle and has central symmetry: in the specific layout, the first thruster is placed at the center of the basic generating element regular hexagon, and the basic generating element regular hexagon Thrusters are also placed on the six vertices, and the side length of the regular hexagon is used as the interval, and other thruster positions are derived from the outward expansion. The number of devices is determined by the required array size. The characteristic of the thrusters thus obtained is that each thruster will be distributed on a certain circle centered on the center of the regular hexagon of the basic generator; multiples of 6 thrusters are di...

Abstract

The invention relates to a layout method for a micro attitude and orbit control thruster array. In order to solve the problem that the conventional thruster array is unsuitable for orbit control, the invention provides a regular hexagon-based thruster array and respectively designs a micro-thruster array-based thruster allocation algorithm according to functions to be realized, namely attitude control and orbit control, wherein the array can avoid an eccentric thrust due to the algorithm, and can rapidly and accurately find the needed coordinate position of each thruster by using a distribution rule of the thruster in the array and a related control algorithm. The layout method for the micro attitude and orbit control thruster array has the advantages of improving the utilization rate of the thruster in the array and effectively avoiding ending the service life of the array too early.

Description

technical field [0001] The invention relates to a layout method of array thrusters of miniature attitude-orbit control thrusters. Background technique [0002] With the development and application of micro-satellites, it also poses challenges to its high-precision attitude and orbit control, which requires actuators with small mass and volume, high integration, low power consumption, and high reliability to provide small and precise impulses , while the micro-solid thruster array can meet the requirements of the micro-satellite attitude and orbit control system. The micro solid thruster array can integrate high-density micro thrusters. Each thruster unit generates a tiny impulse, which can realize any combination of ignition and variable thrust control. The outstanding advantage of this thruster is that it can be applied to kilograms Pico-satellite or nano-satellite is a new type of satellite control power device. [0003] With the gradual deepening of the research on micr...
