Abstract : A fault isolation and identification method for nonlinear dynamic systems is proposed. The method is based on parameter intervals with adaptive thresholds. Its isolation speed is fast. It provides immediately the estimate of the system faulty parameter value after the fault isolation. The superior and inferior bounds of the faulty parameter are also given. Along with the operations of the correspondent adaptive observer, the estimate of the system faulty parameter becomes more and more precise.
