摘　　要：该文原理性地设计了一种基于流体故障知识岛的压力流量复合容错控制模块,并对自行设计的流体故障知识岛的压力和流量感知控制模块进行了仿真分析,对压力和流量感知控制模块的容错控制性能进行了研究。通过分析仿真结果,证实本文设计的基于新型液压容错技术流体故障知识岛的压力流量复合控制模块能够提高实际液压系统的可靠性和安全性,具有重要的实际应用价值。In this paper, a kind of pressure-flow compound fault-tolerant control module based on Knowledge Modules of Hydraulic Fault （KMHF） is designed rationally. The simulation analysis of the pressure-flow perceptible control module based on KMHF has been made and the fault-tolerant properties of the pressure-flow perceptible control module have been studied. By analyzing the simulation results, it turns out that the pressure-flow compound control module based on KMHF as a new hydraulic fault-tolerant technology present in this paper can improve the reliability and safety of practical hydraulic system and has important application value.
