摘　　要：为了解决现代机电系统发生故障后,传统的故障诊断与停机维修方式无法适用的问题,提出了故障自愈的思想。借鉴自然界的免疫原理,建立了故障自愈系统与免疫系统之间的映射关系,研究了基于免疫原理的故障自愈系统。以电液伺服系统为对象,使用AMESim软件建立仿真模型,仿真并分析了电液伺服系统故障,设计了基于免疫原理的电液伺服系统故障自愈。仿真实验结果表明了该系统的可行性和有效性。In order to solve the problem that the traditional way of fault diagnosis and maintenance downtime unable to apply when failures of modem mechanical and electrical system occurred, the idea of fault self-healing was put forward. Referenced to the immune principle of nature, the mapping relationship was established between fault self-healing system and the immune system, and a fault self- healing system based on immune principle was studied. The simulation model of electro-hydraulic servo system taken as an object was established through AMESim software, and its fault self-healing was designed based on immune principle after simulation and analysis of the system fault. The simulation results show the feasibility and effectiveness of the system.
