双线性故障检测观测器 BFDO
提出一种基于传感器最优配置的故障检测观测器设计方法。
A design of fault detection observer based on optimal sensor location is proposed.
针对线性时不变动态系统，给出了故障检测观测器设计问题的描述，采用后置滤波器达到对故障具有尽可能大的灵敏度，而同时对未知输入信号的影响具有尽可能强的鲁棒性目标。
Using post-filter can reach the aim when the system is designed to be as possibleas sensitive to faults and simultaneously as possibleas robust to the unknown inputs such as disturbance.
仿真算例结果表明，在故障发生时，优化观测器可以很灵敏地检测出故障，并能将未知扰动对残差的影响有效地抑制在给定的范围内。
Simulation results demonstrate that the proposed observer can detect the faults sensitively, and the influence of unknown disturbance on residual error can be restrained to a given range.
