现代飞行器控制的几个科学问题

针对推动控制科学发展的重要背景之一--飞行器控制所面临的科学问题做了介绍.全文分4个部分:①阐述飞行器控制所受的物理学上的支配,包括由于坐标系之间相对运动引起的问题,运动体所受的单边约束和不可积的非完整约束等;②讨论了由于运动复杂性需求而提出的多作动器的动态配合问题和异类传感器在需经过信息融合情况下由测量输出重构系统状态问题;③飞行器系统本身存在的各种运动模式之间的耦合,例如不同飞行通道的耦合,姿态与轨道的耦合,刚体运动与弹性体变形运动之间的耦合等;④阐述了关于多目标间的折衷、强时变、强非线性问题.最后指出,从飞行器的实际需求出发提炼问题进行研究,不仅对飞行器本身十分重要,而且将会有力地推动控制科学的发展.

Several Problems on Control of Modern Aerocraft

This paper addresses several key problems on control of modern aerocrafts.After a short introduction, the paper mainly discusses(i) Various physical constraints on modern aerocrafts, including the problems caused by the relative motion of different coordinate systems, unilateral physical constraints and nonholonomic constraints on aerocrafts;(ii) Dynamic control allocation of heterogeneous actuators and state reconstruction based on multi-sensor information fusion;(iii) Various interconnections in the motion of modern aircrafts, including the coupling in different flight channels, the coupling in the attitude and trajectory and the interactions between elastic and rigid effects, etc.;(iv) Trade-off among different objectives, Strong nonlinearities and time-variation problems in modern aircrafts.Finally, it is pointed out that the settlement of these problems and the consideration from the practical requirements of aircrafts are important not only for control of aerocrafts but also for the development of control science.
