This paper is concerned with the fault isolation problem for T-S fuzzy systems with sensor faults. With the help of a set theoretic description of T-S fuzzy models, a new fault isolation scheme is proposed. It consists of a set of fuzzy observers and each of them corresponds to a specified sensor, where the antecedent and consequent parts of the observer are independent on the sensor output. Different from the existing approaches, the premise variables, which do not depend on the specified sensor output but depend on the other sensor outputs, are used in the proposed observer, which has the potential to lead to a better fault isolation performance. In the end, an example is given to show the effectiveness of the fault isolation method.
本文研究了具有传感器故障的 T-S 模糊系统的故障隔离问题。借助 T-S 模糊模型的集合论描述，提出了一种新的故障隔离方案。它由一组模糊观测器组成，每个观测器对应一个指定的传感器，其中观测器的前件和后件与传感器输出无关。与现有方法不同，所提出的观测器中使用了不依赖于指定传感器输出但依赖于其他传感器输出的前提变量，这有可能导致更好的故障隔离性能。最后，通过一个实例说明了故障隔离方法的有效性。
