中文摘要： 气动布局的发展使得飞行和推进系统间耦合更为紧密，飞机的总体性能不仅取决于飞行、推进系统各自的性能，更重要的是二者间的协调，是一个典型的多系统、交叉学科综合优化控制问题。 新型高效率分布式推进布局由于采用附面层吞吸和翼面流场控制技术，使得气动、飞行与推进系统间的耦合效应更加强烈，其在耦合机理和优化策略上与传统飞/推综合控制存在明显差别。因此飞/推综合优化控制研究就成为分布式推进飞机面临的关键问题。 本项目针对分布式推进构型，探索此类对象气动/飞行/推进多系统复杂耦合特性规律；针对新构型下附面层吞吸和翼面流场控制带来的扩展优化空间，提出飞行/推进一体化新型优化控制策略，并研究适于多变量多约束、高复杂系统综合寻优的优化方法，以期为此类对象飞/推综合优化控制提供可行的技术途径。预期成果将为高经济性民用、商用飞机的总体研究提供基础理论支撑，同时也将有助于推动飞/推综合控制领域理论及应用技术的发展。

英文摘要： The Development of aerodynamic configuration makes the flight and propulsion systems tightly coupled. The overall performance of aircraft not only depends on the individual subsystems, it also depends on the coordination between the flight and propulsion systems, which has become a typical integrated optimal control problem for interdisciplinary multi-systems. The high-efficiency distributed propulsion configuration utilizes several new technologies, such as boundary layer ingestion (BLI) and wing flow control, and the coupling influence of aerodynamic,flight and propulsion systems is certainly enhanced. For the new configuration, the coupling effects and optimal strategy of integrated flight/propulsion control is certainly different from current approach. And then basic researches on the integrated flight/propulsion optimal control for distributed propulsion aircraft are very significant. For the distributed propulsion configuration, the characteristic and coupling influence of aerodynamic/flight/propulsion multi-system will be explored firstly. Considering the extended optimization space of BLI and wing flow control, the new integrated flight/propulsion optimal control strategy will be presented and analyzed in detail. Additionally, the optimization algorithm for the multi-variable and multi-constrains complex
