Control-oriented credibility assessment of air-breathing hypersonic vehicle model

摘要

A new control-oriented credibility assessment method of air-breathing hypersonic vehicle model is presented in this paper. As the actual aerodynamic parameters are few, a new method of obtaining linear systems of the Model Awaiting Assessment (MAA) and the Actual Model (AM) is presented to comprehensively evaluate the changing trends of flight conditions. In order to assess the credibility of hypersonic vehicle, the B type association degree is proposed to assess the distinctions between the simulation results of the two corresponding linear systems which are calculated from MAA and the AM. The application is provided to demonstrate the effectiveness of the creditability evaluation method.
