PROBLEM TO BE SOLVED: To provide an observation device and an observation method for physical phenomena which can significantly reduce a data amount used in computation as compared with conventional ones, and can be applied to wide-ranging fields.SOLUTION: A pressure transducer detects pressure fluctuation in a combustion chamber of a gas turbine model combustor, and outputs it as a pressure fluctuation signal. A waveform of the output pressure fluctuation signal is converted to a trajectory on a phase space, and a translation error is computed from the trajectory. By comparing the translation error with a threshold, occurrence of blowout is estimated, and a target value of a secondary fuel flow rate is set. By controlling the secondary fuel flow rate to approach the obtained target value, a combustion condition is controlled. |
