  • Patent number: 10985681
    Abstract: The present invention relates to a generator control system that includes a generator, a variable displacement pump, a generator speed sensor, and a generator speed controller. The generator speed sensor generates a measurement output signal that corresponds to the speed of the generator. The generator speed controller generates a control signal that controls the displacement of the displacement pump to limit generator speed surging. The generator speed controller applying default commanded event control gain values to the control signal when a commanded change in the load or speed of the engine or generator occurs, applying uncommantled event control gain values to the control signal in the absence of a commanded change in load or speed of the engine or gen erator, and reducing the uncommanded event control gain values as needed until the magnitude of generator speed surging is less than a threshold value or until a minimum uncommanded event control gain value threshold is reached.
