Abstract
PURPOSE: To enable to obtain the optimum control response by a method wherein a fuel flow control loop is provided with a means for generating a cascade/local state change-over signal, and the gain for one-round loop is determined based on the signal and each of set points of distribution ratio setters.
CONSTITUTION: A variety of fuels having different calorific values per unit flow rate are passed through respective fuel pipe systems 16-1, 16-2, 16-3 and are fed to a burner part 15 while being controlled to heve respective target values by a fuel flow rate controller consisting of flow rate detectors 17-1, 17-2, 17-3, recording regulators 18-1, 18-2, 18-3 and operating ends 19-1, 19-2, 19-3 which are provided in the pipe systems. A demand heat amount command signal system extending from a fuel-air ratio controller 24 to the distribution ratio setters 25-1, 25-2, 25-3 of the loop system is provided with a loop gain correcting calculator 28 which determins the gain for one-round loop. Accordingly, the response properties can be enhanced by regulating the target value on the cascade side so as to compensate for the difference between the target value on the cascade side and that on the local side.
