英文摘要： This project focuses on the critical problem which is existed in modeling and control for a hypersonic vehicle. Control-oriented modeling and polytopic linear parameter varying (LPV) switching control method for the hypersonic vehicle is investigated, respectively. By analyzing nonlinear, time-varying and coupling characteristics，a control-oriented integrated model of the hypersonic vehicle is developed. For large-span maneuver flight control, the flight envelope is divided into some dynamic sub-regions and the polytopic LPV model is developed for each dynamic sub-region. Then, a state feedback switching control method for the hypersonic vehicle is presented in this project. Further, considering state feedback controller can't be easily applied because some aircraft states can't be measured. Therefore, an LPV output feedback switching control method based on polytopic LPV state observer is addressed. The problem of closed-loop system stability and the dynamic sub-region control performance is analyzed based on multiple parameter-dependent Lyapunov functions. In order to show the effectiveness of the presented method, the hypersonic vehicle visual simulation verification system will be studied. This project will develop a integrated approach for modeling, control and simulation verification and provide an importa
