摘要
在对模糊定性仿真算法改进的基础上,提出了一类信息不完整动态系统的实时半定量故障预报方法。该算法综合利用了系统定性微分方程组、专家经验知识以及系统部分测试数据等关于系统的不完整信息。这些不完整信息在工程实际中比较容易获取,因此该方法比已有的故障预报方法能够更好地处理实际问题。仿真实验验证了该算法的有效性。
Based on improvement of fuzzy qualitative simulation algorithm,a new semi-quantitative and real-time fault prediction method of a class of dynamic system with incomplete information is proposed.In this method,the qualitative differential equation,expert knowledge and a part of testing data about the system which can be obtained easily in the engineering,are used synchronously,so the method can deal with ac- tual problem.The efficiency of the proposed approach is verified by the simulations.
