Abstract:

Some theoretical problems in the application of nonlinear dynamic inversion method to flight control systems are studied. Singh's algorithm is used to show the equivalence of the two current main design algorithms, and the decoupling construction of the nonlinear dynamic in version is regained by the method of inverse system, whose advantages are beneficial to engineering application and interpretation. In the sense of Singhs algorithm, the definition and related features of the first order inverse system are obtained, which are often used in designing flight control systems.

Key words: nonlinear dynamic inversion, inverse system, decouple, flight control system
