Abstract: A gas engine assembly includes a compressor, a combustion system, a bypass line and a control system. The control system is configured to control gas supply parameters based on a transportation delay value. The transportation delay value corresponds to a delay between a time when a gas supply control mechanism is adjusted and a time that gas having a corresponding adjustment of a gas characteristic is received at a predetermined point downstream from the gas supply control mechanism.

Abstract: An apparatus includes a DC-link, a voltage converter, a bus voltage controller, and a supervisory controller. The voltage converter is configured to convert a first DC voltage into a second DC voltage based on a command signal and based on an adjustment signal and to supply the second DC voltage to the DC-link. The bus voltage controller is configured to iterate calculation of the adjustment signal to communicate each iterated calculation of the adjustment signal to the voltage converter. The supervisory controller is configured to iterate calculation of the command signal and to communicate each iterated calculation of the command signal to the voltage converter and to the bus voltage controller. A frequency of the bus voltage controller to communicate each iterated calculation of the adjustment signal is higher than a frequency of the supervisory controller to communicate each iterated calculation of the command signal.
