Summary:PROBLEM TO BE SOLVED: To provide an automatic combustion control system, in which a response speed is improved, while keeping constant the air/fuel ratio of the entire combustion control system. SOLUTION: The automatic combustion control system comprises a double- cross limit combustion controller, a combustion-load sudden change judging part 83, a parameter computing part 84, and a corrective computation part 85. The double cross-limit combustion controller controls a fuel flow-rate control system and an air flow-rate control system. These systems control respectively fuel flow-rate and air flow-rate supplied to a combustion part, so that the ratio between the fuel and air flow-rates becomes constant on the basis of values set respectively in accordance with combustion loads. The parameter-computing part 84 performs computation on parameters for air flow-rate upper and lower limits so as to accelerate the response in control of a sudden change of combustion load. A computing part 85 obtains a correction value in order to correct a flow-rate-setting signal inputted in an air flow-rate regulator so as to accelerate the response in a sudden combustion-load change.
