ANALYSIS FOR SENSOR FUNCTIONAL REDUNDANCY IN FAULT-TOLERANCE SYSTEM

摘要：

Employing theory on state observer, analyse the functional redundancy of sensor failure in fault-tolerant control system. According to the separation theorem of generalized system, the feedback gain matrix and observer gain matrix are designed in condition of sensor strong functional redundancy as will as weak functional redundancy. Then the parameters of them could be adjusted to carry out faulttolerance to make failed closed-loop system stabile. But under the non-functional redundant, the system is unstable. Finally get the response curves of the system by computer simulating.
