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.
