| Abstract: | Aiming at the aircraft dynamics model that can be described by linear parameter-varying(LPV) system,the graphics approach to establish the Linear Fractional Transformation(LFT) model is applied and the Kalman decomposition is used to reduce the order of the LFT model.Finally,the aircraft dynamics is explicitly separated into certainty part and time-varying parameter part.The validity of the established model is verified by the mathematic simulation. |
