ABSTRACT:
A speed regulating governor system is disclosed for a small internal combustion engine having a throttle valve the position of which affects the speed of the engine, wherein the governor system includes a mechanical proportional controller and an electromechanical integral controller. The throttle valve is mechanically linked to and controlled by a governor lever that is acted upon by opposing forces provided by a mechanical speed selector and a centrifugal flyweight apparatus which measures the engine speed. Additonally, a solenoid actuator is operably connected to the governor lever to apply a force thereto in response to a control signal generated by an electronic integral controller. The control signal is proportional to the time integral of the difference between a desired electrical speed input and the actual speed of the engine measured by an electrical signal generated by an alternator driven by the engine.
