三余度机电伺服机构及其故障隔离与重构技术

Technology of Reconstitution and Fault Isolation for Treble-redundancy of Mechanical and Electrical Servo Mechanism

为了提高运载工具姿态控制伺服机构的可靠性,提出一种三余度的机电伺服机构,在三余度机电伺服机构基本方案的基础上,开展了故障模式分析和仿真,进行三余度机电伺服机构故障辨识和故障隔离研究,得到了故障重构的设计思路,并对三余度机电伺服机构进行验证试验研究。

In order to improve the reliability of shuttle attitude control servo mechanism, This paper presen- ted a treble-redundancy of mechanical and electrical servo mechanism. On the basis of analyzing the treble- redundancy of mechanical and electrical servo mechanism, carry out the fault mode analysis and simulation and researches the technology of treble-redundancy of mechanical and electrical servo fault identification and fault isolation. The fault reconstruction design train of thought was got. The experiment study show that the system is feasible.
