高超声速飞行器用模块化集成式容错伺服系统研究

The hypersonic flight vehicle is a kind of the new-generation high-performance weapons and equipment. The dynamic quality and comprehensive performance of the flight vehicle control system are directly determined by the performance of the servo system. However, the conventional hydraulic and fly-by-wire servo system cannot meet the stringent performance requirements of the hypersonic flight vehicle, such as high fault-tolerant capability, high dynamic response and high load carrying capability. In this project, we propose a kind of modular and integrated fault-tolerant servo system, which can sufficiently use the high fault-tolerant capability of multiphase permanent-magnet machine and the high load-carrying capability of planetary roller screw, and the proposed servo system can radically meet the stringent performance requirements of servo system for hypersonic flight vehicle. The electric, magnetic, thermal design principle and design method of the modular multiphase fault-tolerant permanent-magnet machine are investigated. Then the integrating design method of the modular multiphase fault-tolerant permanent-magnet machine and the planetary roller screw are studied. Further the fault diagnosis method and fault-tolerant control strategy of the modular and integrated fault-tolerant servo system are investigated. The drive and control technology that feature both strong anti-interference and high power density are also developed. A prototype will be manufactured and experimental research will be carried out accordingly. The specialized theory, engineering design and analysis method will be obtained for this kind of servo system. The research achievements are conducive to advance the development of military weapons and equipment, and they are also beneficial to improve the combat capability, which have significant scientific importance and national defense application value.
