摘要：本文给出了通用故障模型、故障检测方法、故障可检测与诊断的充要条件及故障估计的三级分解算法。仿真工作表明本方法是有效和可行的。
In this paper, a general fault model, the necessary and sufficient conditions for detectability and diagnosis of fault in linear system, as well as three-decomposition algorithm for fault estimation have been proposed. Intensive simulations show that the technique not only can determine whether there are faults but also can estimate the process state and fault variables in the system. It is an advantage to use three-decomposition algorithm and the accuracy and velocity of estimation are greatly increased.
