Fault Tolerance for Active Surface System with Actuator Faults

Table 2

Active surface fault diagnosis method based on artificial intelligence [13–15].

Method	Advantage	Limitation
Expert system	Strict reasoning logic, high reliability	Knowledge is difficult to obtain, complex reasoning
Fault tree	Qualitative, quantitative analysis with logical reasoning	The construction process is heavy and difficult. Logical operations are prone to error
Neural network	Parallel processing, self-learning, self-organization,	The reasoning process of diagnosis is not clear
Fuzzy inference	Flexible enough to deal with uncertain information	It is difficult to establish rules and membership functions
