This article describes the configuration and working principle of the high-temperature combustion system; according to the control requirements which have a wide range and high precision for fuel flow-rate of the high-temperature combustion system, a set of fuel supply system is designed based on the frequency conversion hydraulic technology and electro-hydraulic proportional technique. An automatic control system with the function of field and remote control is carried out to achieve the precise supply of the fuel. The transfer function which describes the dynamic characteristic of the fuel supply system is given and the dynamic matrix control algorithm is employed to realize the high-quality control of fuel flow-rate. The experimental results show that the response time of flow-rate is about 12 s, almost no overshoot, and control accuracy within 1%. Therefore, the designed fuel supply system can meet the requirements of the high-temperature combustion system, and the designed control system has good control performance.
