Abstract
In this paper the role of the speed governor and some of its techniques are reviewed. The adopted
governor is an electronic speed governor based mainly on analogue computations. Here the speed of the
prime mover is governed by an analogue signal extracted from the real frequency of the voltage generated
by the coupled alternator. The implemented system senses frequencies in the range of ±10% of the nominal
frequency (fo) of the generated voltage and tends to fix the frequency of the generated voltage at fo .
The system is identified by a fast and controllable response. The associated errors of the whole
system are almost negligible.
