the chemical reaction (combustion) between the high-speed
gas and kerosene, which makes uncertainties and external
disturbances in the system, and the control difficulty is further
increased because of the high control requirements of
accuracy and the range of the temperature. Therefore, it is
difficult to achieve a satisfactory result by using traditional
control methods. Although the intelligent control which
developed recently brings dawn to the process control, its
theory is not perfect, theoretical research is more than practical
application. Therefore, a control method is urgent need to be
carried out for the precise control of the gas temperature.
