中文摘要：

将依赖于系统数学模型和依赖于故障特征信息的两类故障诊断方法相融合，提出了一种基于模糊理论综合故障诊断新方法，并以非线性系统故障诊断为例，给出了综合故障诊断系统的结构和故障诊断的具体实现方法。本方法不仅可以扩大故障诊断的范围，而且又能紧密联系工程实际。最后，以异步电动机常见故障的诊断为具体实例，验证了方法的可行性和有效性。

英文摘要：

Based on Fuzzy theory, a new comprehensive fault diagnosis approach was presented by combining the systems model-relied method with the fault information-depended strategy. The construct of the comprehensive diagnosis system and the method to accomplish fault detection and diagnosis were discussed by an example on nonlinear systems. The comprehensive approach can expend fault diagnosis bounds, and can link to the engineering practicality nearly. An AC motor familiar fault diagnosis was studied to explain that the approach is feasible and valid.
