Abstract:

For the failure of construction of self repairing flight control systems, the methods of mode identification and parameter estimation based on exact linearization on original space and characteristic space are presented. And the methods for mode identification and parameter estimation based on two hypotheses and multiple hypotheses(enhanced type) statistics are provided. The decision rule of identifiability and estimability,for the failure of construction, is given, followed by the digital simulation of a kind of fighter.

Key words: fighter, failur e of constr uction, mode identification, parameter estimation
