摘　　要：一种不依赖硬件和环境的全软件解决方案,直接利用输入信号和反馈信号的测量分析,经模糊变换获得信号特征模糊变量,通过扫描信号特征量的超限情况,调用相关推理规则运算求解得到控制系统的故障诊断信息。开发的应用软件已用于工业实际系统。This fault diagnostics approach is based on directly analyzing the input signals and feedback signals from the system, not depended on any hardware. The fuzzy variable of signal characteristic is obtained by fuzzy transform. The fault diagnostic information of the control system is gained by scanning out of gauge of signal characteristic quantity and calling fuzzy reasoning rule's computation. The application program has been developed in MCU (micro control unit) for the control engineering.
