Abstract

PURPOSE:To simplify the configuration of the digital pitch control system by controlling a program counting with a computing circuit for producing a specific set frequency dividing ratio. CONSTITUTION:The output frequency f0 of a crystal oscillator 1 is divided in frequency by the frequency divider 4 as a program counter, thereby obtaining desired output frequency (f). The frequency divider 4 as the program counter responsive to the set frequency dividing ratio (n) as control input divides the frequency into 1/n. The set frequency dividing ratio (n) of the divider 4 is n=n0/ (1+alpha/100), where the frequency dividing ratio to obtain the output frequency fS as reference is represented by n0 and the rate of change of the output frequency relative to the reference output frequency is represented by alpha%. The output of the frequency divider 4 is applied to the rotary machine 10.
