| 摘 要： | 为解决液压系统故障诊断过程中存在的大量不确定性信息,提出一种基于改进的模糊Petri网故障诊断算法。将虚库所和虚变迁引入到模糊Petri网算法中,解决了变迁是否触发以及最后故障事件模糊概率值的确定问题,使算法更符合实际和数学推理。结果证明了该改进算法的适用性和可行性。

| Abstract: | In order to solve the problem of plenty of uncertain information in the process of fault diagnosis of hydraulic system,propose a fuzzy Petri net in fault diagnosis algorithm.It imported the concept of false place and transition into fuzzy Petri net algorithm to solve transition trigger and last fault fuzzy probability value ensuring,so the algorithm would be better in accord with the practice and math reasoning.The result shows that this algorithm is applicable and feasible. |

| Keywords: | fuzzy Petri net false place and transition hydraulic system |
