<p><P>PROBLEM TO BE SOLVED: To provide a speed governor controlling method and device equipped with enhanced starting characteristics so that the speed of any object to be controlled such as a water wheel generator increases quickly and stably to the target revolving speed. <P>SOLUTION: The value of the degree of guide vane opening calculated from a static head signal 13 and a static head vs guide vane opening function 14 is from zero added to the output of a PID computing part 11 in the time setting identical to the speed increasing rate conforming to the start signal. <P>COPYRIGHT: (C)2003,JPO</p> |
