Supervise gas turbine speed and axial load to control exhaust temperature

Fuzzy logic is a suitable tool for building the supervisory control laws with the following objectives: * Determine the fuel flow (the reference signal controlling the fuel flow FSR), depending on the rotational speed * Obtain the exhaust temperature control over a range of ambient temperatures.

Summary:Fuzzy logic is a suitable tool for building the supervisory control laws with the following objectives: * Determine the fuel flow (the reference signal controlling the fuel flow FSR), depending on the rotational speed * Obtain the exhaust temperature control over a range of ambient temperatures. [...]permanent overheating is possible if the efficiency of the compressor and the gas turbine are deteriorated. [...]the measuring and recording of TExhaust is classified for simple display, for alarm or to halt startup. In this study, the gas turbine supervision consists of three control loops: * Room temperature control-i.e., temperature at the compressor intake, T¡ = TA * Turbine combustion chamber temperature control, TCC * Turbine shaft rotational speed control, N. Temperature and speed controls are activated during an abnormal operating state, where the maximum power of a gas turbine exceeds the operating limit, which depends on the shaft speed and the ambient temperature. [...]the turbine efficiency and the useful work (and, therefore, the power) decrease.
