摘要
液体火箭发动机减损与延寿控制技术是一门横跨控制理论与技术、材料科学、发动机技术等领域的新兴交叉技术,是工程上实现液体火箭发动机健康监控系统故障控制功能的核心技术之一。主要阐述了可重复使用液体火箭发动机智能减损与延寿控制技术的基本概念与原理,剖析了该技术的系统框架与关键技术,指明了存在主要的技术问题和今后的发展趋势。
A survey on the techniques of intelligent Damage-Mitigating (DM) and Life-Extending (LE) control for Reusable Liquid-propellant Rocket Engines (RLRE) was presented. Firstly, the fundamental concepts and principles on DM and LE control were clarified. Then, the key technologies including system modeling and analysis, damage modeling and estimation, and techniques on design and realization of the DM controller and LE control algorithms were analysed in details. The key technology problems and trend were also indicated.
