PROBLEM TO BE SOLVED: To solve problems that a power generator can hardly be controlled at such a number of revolutions (rpm) that is suitable for a good turbine efficiency and the turbine efficiency can hardly be maintained at a high level, since a command value of rpm is converted from a load voltage assuming that a turbine output capacity is directly proportional to rpm, and fuel is adjusted by performing a rpm control according to the command value of rpm in a prior art. SOLUTION: A speed control of the power generator is performed always by a transducer connected to the power generator, and a command value of speed is determined in such a manner that optimum speed command is prepared from a quantity of state of the turbine.
