摘　　要：针对目前大部分序贯多故障诊断算法需要计算最小碰集、计算方法较为复杂的问题,在对多故障相关矩阵模型进行转换的基础上,利用Rollout算法对基于信息熵的多故障诊断策略进行优化,提出一种新的多故障诊断策略.实例计算结果表明,与现有算法相比,所提出方法的期望测试费用更低,且具有先测试后修复的特点,在实际工程中更便于操作.At present, most of the existing sequential multiple fault diagnosis algorithms have to compute minimal compact set, which is very complex. On the basis of converting the fault-test relation matrix, the diagnosis strategy for multiple faults is improved by using Rollout algorithm. Then, a new diagnosis strategy for multiple fault diagnosis is proposed. The example demonstrates that the cost of the method is lower, and the method can test first and repair last, which is useful in practice.
