Abstract

Since the hypersonic aircraft adopts plane-symmetry configuration, BTT flight control and airframe-engine integration design, the three channels couple obviously, resulting in ineffective of classical control theory. This paper proposes a comprehensive decoupling method. The method defines an evaluation index of coupling influence. The coupling factors can be equivalently transformed or ignored and dynamic model of aircraft is decoupled Therefore it is helpful for using classical control theory and evaluation method to solve the control problem of hypersonic aircraft. By digital simulation, the decoupling method is proven effective and has good robustness for uncertainties as well.

Key words： coupling model; comprehensive decoupling method; degree of coupling; dynamic model
