导弹质量矩控制技术发展综述

Key Technique and Development for Moving Mass Actuated Kinetic Missile

质量矩技术是近年来导弹控制领域研究的热点问题之一。它是通过调整弹体内部活动质量块的状态来实现导弹机动飞行的。与传统的气动舵控制方式相比,它具有响应快、气动外形简单、无舵面烧蚀问题等优点,在大气层内高超声速飞行控制领域具有广阔的应用前景。简述了质量矩技术的原理及应用领域,回顾了导弹质量矩控制技术的发展历程;从总体布局、动力学建模、控制系统设计等方面综合分析了质量矩技术的研究现状;提出了一些当前需要解决的难点问题,供相关人员参考。

Moving mass control is one of the most remarkable aspects in the field of control technology of missile in recent years. In this method, the moving mass is adopted to control the flight of the missile. The disadvantages of traditional pnemnatic actuator control for missiles are overcome including slow response, complex aerodynamic shape and rudder surface ablation etc. Therefore it can be used in the field of hypersonic flight control within the atmosphere. In this paper, the principle and applications of moving mass technology were described, development of moving mass control was reviewed, research trend including the overall layout, dynamic modeling, control system design were analyzed, Several problems were mentioned for relevant personnel, these still need to be solved.
