发动机诊断系统 meaning in Chinese

engine diagnosis system

In this thesis , the qualitative - model - based fault diagnosis methods for a liquid - propellant rocket engine ( lre ) are studied in order to provide ones with novel approaches to build the fault diagnosis system , which possesses good robustness , real - time operating ability and practicability . the qualitative - model - based fault diagnosis methods hopefully substitute for quantitative - model - based methods for their limitations of computational complexity , robustness and practicability , and for the traditional rule - based method for its limitations of the acquisition of knowledge and flexibility
本文主要研究液体火箭发动机基于定性模型的故障诊断方法，其目的是为建立具有良好鲁棒性、实时性和实用性的发动机诊断系统提供一条新的技术途径，以期克服定量模型方法计算复杂、鲁棒性差、不便应用的缺陷，克服传统的基于规则方法知识获取困难和灵活性差的缺点。
