  • Publication number: 20220286069
    Abstract: To provide a generator control device that, even when communication with an external control device is interrupted, evaluates independently, and can increase an amount of power generated so that a drop in DC voltage can be restricted preemptively, while restricting a fluctuation of rotational speed. A generator control device determines that a voltage drop prediction time control is executed when it is predicted that a drop of the DC voltage will be large; generates a rectangular pulse wave such that a duty ratio increases gradually during the excitation time when determining that the excitation control rotational speed condition was fulfilled, and the voltage drop prediction time control is executed; and changes the duty ratio so that the detected value of the DC voltage nears the increased target voltage when determining that the excitation control rotational speed condition was not fulfilled, and the voltage drop prediction time control is executed.

  • Patent number: 10896074
    Abstract: An interactive processing device according to an embodiment acquires one/more items' information for predetermined operation through interaction with a user, and includes one/more itemized-processing-units and an interaction-control-unit. The itemized-processing-units corresponds to the items. The interaction-control-unit controls the interaction collaboratively with the itemized-processing-units. The interaction-control-unit transmits user-input information to each itemized-processing-unit. Each itemized-processing-unit extracts a candidate for to-be-acquired information and transmits the candidate to the interaction-control-unit with likelihood information of being the to-be-acquired information. The interaction-control-unit determines a candidate having first-threshold-satisfying likelihood as information of an item corresponding to the candidate-transmitted itemized-processing-unit. When undetermined information item exists, the interaction-control-unit outputs inquiry for the item information.

  • Patent number: 10804828
    Abstract: To provide a generator controller can determine permission of power generation autonomously within a range where startability is not deteriorated, even in the case where the generator controller cannot communicate with the engine controller. A generator controller, in case of communication normal time with engine controller, permits the generation voltage control when the permission command signal is received from the engine controller and the generator rotational speed is higher than a determination value at communication normal time, and prohibits the generation voltage control at other times; in the case of communication failure time, permits the generation voltage control when the generator rotational speed is higher than a determination value at communication failure time, and prohibits the generation voltage control at other times.
