【摘要】 故障诊断指根据系统特征确系统是否发生了故障,如果发现系统发生了故障,进一步确定故障发生的部位和对应的元部件。基于灰色定性仿真的故障诊断理论是根据系统的现实状态与用灰色定性仿真预测的系统的状态的差异判断系统是否发生了故障,若故障出现,通过故障状态与故障模型的匹配确定故障的类型的一种新型故障诊断理论。更多还原

【Abstract】 A fault diagnosis is a method to confirm whether a system take place faults via the system states and to find out,further,the relative components if faults occurred.The fault diagnosis theory based on gray qualitative simulation(GQSIM) is a new theory that judge whether a system take place faults according to the difference between the system’s real-time states and forecast states by GQSIM and make sure the fault styles via matching the faults states and fault models.更多还原
