近空间高超声速飞行器对控制科学的挑战

本文分别从6个方面讨论高超声速飞行器对控制科学带来的挑战：1）高超声速飞行器强耦合特征，解耦与耦合协调控制的区别与联系；2）高超声速飞行器异类多作动器的协调配合，以及冗余控制输入和一体化设计带来的控制科学问题；3）流体力学与控制的结合，面向控制的建模理论与方法；4）高超声速飞行器中相关的经典非线性、时变、优化与变分问题；5）高超声速飞行器控制过程中的飞行分段与问题分解；6）重视计算机的作用，有效结合计算机仿真解决工程问题．从高超声速飞行器实际需求出发提炼问题并加以解决，不仅对飞行器本身非常重要，而且会推动控制科学的发展．

Challenges of control science in near space hypersonic aircrafts

This paper discusses challenges faced by control science for hypersonic aircrafts in six aspects: 1) coupling characteristics of hypersonic aircrafts, differences and connections between decoupled and coupled control; 2) Coordinated control of heterogeneous actuators for hypersonic aircrafts, and scientific problems in multiple control inputs and unified design; 3) combination between fluid dynamics and control, and control-oriented modeling method; 4) canonical nonlinear, time-varying and optimizing problems for hypersonic aircrafts; 5) flight section and problem decomposition for hypersonic aircraft control; 6) relying on numerical simulation more than ever to solve engineering problems in hypersonic aircraft control. The investigation of these problems from practical engineering perspective is not only important for aircraft design in particular but also beneficial for the development of control science.
