Today, gas turbines are one of the major parts of

modern industry. They have played very imported in

aeronautical industry, power generation, and main mechanical

drivers for large pumps and compressors. This paper proposes to

examine the application of fuzzy logic to represent a fuzzy model

of a gas turbine and their applications in control systems. The

main objective of this work is construction of a fuzzy model of the

gas turbine system, the validation results show that this model

can be used for the system control and Diagnostics.
