Abstract: Abstract: In view of the importance of exhaust temperature of gas turbine to the operation of a power unit under offdesign condition, the function and principles of temperature control of inlet guide vane (IGV) were introduced by taking the gas turbine of a combine cycle as a study object. With the conditions of load and ambient temperature changed, the dynamic response process of thermodynamic parameters of gas turbine was compared and analyzed under three different control strategies, ie., pure feedback control, feedforwardfeedback control and double feedforwardfeedback control. The results show that the control characteristic of double feedforwardfeedback control strategy is better than that of other control strategies.
