摘　　要：为提高电液伺服控制系统的稳定性并降低维修成本,根据人工免疫原理,从电液伺服系统内部出发,设计完成对其自身故障的识别与诊断,通过调用自愈策略实现其故障的自愈。利用基于模块化的仿真软件AMESim,构建电液伺服系统的仿真模型,通过HCD库对其中的液压缸仿真模型进行优化设计。在分析其放大器故障的基础上,设计电液伺服系统故障自愈模型。仿真分析结果表明,该模型的可行性和有效性。To improve the stability of the electro-hydraulic servo control system and reduce the maintenance cost,from the inside of the electro-hydraulic servo system,based on the artificial immune principle,the identification and diagnosis of its own fault were designed and completed.Self-healing strategy was used to achieve self-healing of the failure.The simulation model of the electro-hydraulic servo system based on the modular simulation software AMESim was constructed,and the simulation model of the hydraulic cylinder was optimized and designed by the HCD library.Based on the analysis of the failure of the amplifier,the self-healing model of the electro-hydraulic servo system was designed.Simulation analysis indicates the feasibility and the effectiveness of the proposed model.
