Abstract

The invention discloses a novel displacement sensor combination layout and high-reliability redundancy design method. The installation requirement of each displacement sensor is specified, each displacement sensor outputs relative displacement in one direction, and a combination of nine displacement sensors is subjected to layout and reliability improvement redundancy optimizing configuration design from multi-dimensional angles including the installation positions and the measurement directions; a relative position and relative attitude solving algorithm is constructed, high-precision measurement on the high-reliability three-axis relative position and relative attitude is achieved, and the decoupling control requirement on the relative mass center position and the relative attitude of two cabins of a double super satellite platform is met; and by analyzing the solving matrix ranks, the redundancy degrees of the displacement sensor combination are obtained, then the reliability of thecombination is calculated, and the system optimum design is continuously optimized and guided. Accordingly, high-precision measurement on the high-reliability three-axis relative position and relative attitude is achieved, and the decoupling control requirement on the relative mass center position and the relative attitude of two cabins of the double super satellite platform is met.

Description

technical field [0001] The invention relates to a composite control technology for a load compartment of a satellite platform with ultra-high pointing accuracy and ultra-high stability (double ultra), in particular to a novel displacement sensor combination layout and a highly reliable redundant design method. Background technique [0002] The requirements for attitude pointing accuracy and stability of future advanced spacecraft are two orders of magnitude higher than the current level. Traditionally, the fixed-connection design of the load and the platform is adopted, and the dynamic characteristics of the two are deeply coupled, which makes it difficult to achieve the double-exceeding index of the load. Although the active and passive micro-vibration suppression methods have achieved certain results, the defects of the limited fixed-connection design, It is difficult to achieve double super indicators. [0003] The "Shuangchao" satellite platform breaks the traditional f...
