Research Of Self-healing Technique Based On Prokaryotic Bio-inspired Array

Electronic equipments are widely used in spacecraft, and the severe operating environments make them at high risk of failures. The ordinary method to improve the reliability of electronic equipments is multimode redundancies, which is, however, with the shortcoming of limited fault-tolerant ability, poor environment adaptability and etc. Embryonic Array (EA), which is designed by imitating the self-healing ability of multi-cell organism, provides a new solution for improving reliability of the electronic equipments. But it still has the shortage of large memory consumption. What's more, the array structure calls for improvements. Based on this situation, this thesis researched Self-healing Technique based on Prokaryotic bio-inspired Array (STPA). The main contents are as follows.(1) The structure of prokaryotic cells and their communities were illustrated. After studding EA, Prokaryotic bio-inspired Array (PA) was proposed, aiming at EA's deficiencies.(2) The array structure, cell structure and the self-healing methods of PA were researched, and its resource consumption was compared with EA. Self-healing performance of PA and feasibility of STPA were validated, according to the simulation of DBPSK modulator circuit.(3) PID controller based on PA was designed. According to imitate for controlling flight altitude, the control effects before and after adding the faults were analyzed, which validated the self-healing ability of the PID controller and the feasibility and availability of STPA.At the end of this thesis, a summary was made to the research work in the thesis, and some advices for the further work were also proposed.
