Abstract: A generator set control system for minimizing vehicle noise and vibration. The system has sensors at different locations in a vehicle, a generator set with a generator set speed controller, and a system controller operatively connected to the sensors and to the generator set speed controller. Noise and vibrations are measured by the sensors during startup of the generator set, and the system controller determines which generator set speeds are to be avoided. Optionally, a steady state measurement may be used to determine undesirable generator set speeds. The generator set speed controller is commanded to make the generator set avoid the speeds mentioned. The system may be mounted permanently to the vehicle for subsequent measurements as needed.
