本文提出了状态完全可观冗余度的概念.以线性时不变系统为研究对象,采用数值秩计算理论,编制了计算机辅助计算状态完全可观冗余度的程序.在依靠数学模型实现的容错控制系统中,只要选取可保证状态完全可观冗余度为1的量测信号,就能在任一测量传感器失效的情况下,重组状态反馈控制律,以实现容错控制。
In this paper, the concept of completely stateful redundancy of states is proposed. For linearly invariant systems, the numerical rank calculation theory is used to develop a program with computer-aided calculation of complete and appreciable redundancy.In the reliance on mathematical models for fault-tolerant control In the system, the state feedback control law can be reorganized in the case of failure of any measurement sensor, so long as the selection of the measurement signal which can guarantee the complete observable redundancy of 1 states can realize the fault-tolerant control.
