ABSTRACT:
A frequency detector in a frequency control for a generating system includes a system processor and a counter for deriving a digital count proportional to the output frequency of the generating system. The system processor executes a series of control cycles during which the processor controls the speed at which the generating system is driven in accordance with the output frequency. The system processor detects the digital count at a predetermined point in each control cycle and resets the counter to initiate generation of a new digital count. The data from the detector does not require an interrupt handling procedure and hence complexity is minimized.
