%X 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.
