- Abstract
In this paper, firstly, the non-linear longitudinal modeling approach is proposed based on the geometric shape of the typical structure of the hypersonic vehicle as the research object, combined with correlative hypersonic aerodynamic theories, and then local linear models are established near multiple balance points of the overall fuzzy system by utilizing fuzzy Takagi-Sugeno (T-S) modeling based on different areas dynamic characters. An overall non-linear fuzzy model is obtained by the integration of these local models linking fuzzy membership function. Parallel distributed compensation (PDC) control algorithm is proposed based on built T-S fuzzy model by considering the linear state feedback controller for each of the fuzzy local model. Moreover, sufficient condition for the stability of T-S fuzzy system is investigated for the non-linear system which has complex stability analysis by obtaining a common positive definite matrix P that would satisfy a set of Lyapunov inequalities and the state feedback controller gain matrixes K based on linear matrix inequalities (LMI) optimization algorithm. Finally, MATLAB is utilized to realize result simulation to show the effectiveness of the proposed technique, including performance quality and robustness requirements.
