Overview of Fault Diagnosis and Fault-tolerant Control for Nonlinear Systems

A general nonlinear systems model is introduced and the character of fault diagnosis and fault-tolerant control technique for nonlinear systems is analyzed. Based on these results, this paper summaries the research advances and major methods on fault diagnosis and fault-tolerant control technique for nonlinear systems. These methods include： the fault diagnosis algorithm based on sliding mode observer, the fault diagnosis algorithm based on unknown input observer, the fault-tolerant control technique based on nonlinear observer, and the robust fault-tolerant control technique based on H∞ This paper also points out some key problems to be solved in this area and the trends for future research.
