DETECTION AND IDENTIFICATION OF ABRUPT FAULTS IN INPUT COMPONENTS OF DYNAMIC SYSTEM
动态系统输入环节突发性故障的检测与辨识

Under quantitatively analyzing the influence of pulse type faults and step type faults from input components on state and output, a series of new fault detection approaches and magnitude identification algorithm are built, which are combination of onward fault tolerant M type filter with the reverse weighted least squared estimators. As for step type faults, the difference transformation approach and the expanded state space approach are suggested for time invariant and time variant systems, respectively. These new methods given in this paper are practical.
