Study of an engine-generator control system

A study of the voltage control loop and the speed control loop of a diesel-engine-driven alternator has been made, with special attention to the interactions between these loops. Laboratory tests, using both step and sinusoidal disturbances, were made and used as checks on an analog simulation of this system. These studies showed that loop interaction was small. The analog simulation should be useful for other purposes, such as the study of interconnected units and synthesis of improved systems.
