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