Rough Set Diagnostic Frameworks for Gas Turbine Fault Classification

Abstract: Fault classification has become one of the main features in gas turbine health monitoring. Hence techniques such as gas path analysis, artificial neural networks, expert systems, fuzzy logic and many others have been developed for this purpose in the past. In this paper, an alternative rough set based diagnostic method using enhanced fault signatures combined with three fault classification frameworks for gas turbine fault classification have been introduced, i.e. Framework 1 with a single step to classify sin… Show more

“…From the linear GPA method developed by Urban in the late 1960's [13], a series of GPA methods were proposed, such as an adaptive nonlinear GPA method [7], artificial neural networks [3], rule-based expert system and rule-based fuzzy expert system [11], and genetic algorithm [4,12,17]. The merit of artificial intelligence methods, such as neural network, rough set [14], Bayesian network [9,10] and rule based expert system, is that they do not need a gas turbine performance model, as only the relation information between fault symptom and degradation is needed. They can easily isolate the faulty component.…”

“…Many gas-path analysis approaches have been proposed to estimate the performance and health status for gas turbine. From the linear GPA method developed by Urban in the late 1960s [2], a series of GPA methods were proposed, such as thermodynamic model based GPA methods (e.g., adaptive linear and nonlinear GPA methods [3][4][5] and genetic algorithm based GPA method [6][7][8][9]) and artificial intelligence based GPA methods (e.g., artificial neural networks [10,11], rule based expert system [12][13][14], and rule based fuzzy expert system [15]).…”

“…As a method of data analysis, the biggest advantage of rough sets theory is only to provide the data set that need to be processed, and other priori information is not essential, and the algorithm of the theory is simple and easy to operate [13] . Rough sets theory is widely used in artificial strategy decision system, pattern recognition, knowledge mining and other fields [14][15][16] .…”
