Abstract: A liquid ejecting apparatus includes a liquid ejecting unit that performs printing on a target by ejecting liquid, which is supplied from a liquid supply source, from a plurality of nozzles; and a maintenance section that performs maintenance processing of causing the liquid to be discharged from the nozzles. Based on print information for performing printing on the target, in a case where printing satisfying a setting condition presumed such that a staying time of the liquid staying in a liquid path between the liquid supply source and the nozzles during printing is long is performed, a discharge amount of the liquid to be discharged during the maintenance processing that is performed before printing is set to be larger than a discharge amount of the liquid in a case where printing not satisfying the setting condition presumed such that the staying time is short is performed.

Abstract: A device control apparatus periodically transmits a status confirmation signal to a control source device described in a cooperation control table and receives a response signal with respect to the status confirmation signal. Device control apparatus determines whether or not a status included in the response signal matches a status described in the cooperation control table. If they match, a control destination device, an operation and a control command corresponding to the operation are specified using the cooperation control table. A configuration for transmitting a control command with respect to the control destination device is provided. Therefore, even in a case where a communication protocol and the control command are different from one another in makers of devices, it is possible to realize cooperation control.

Abstract: A control device for a power generation system whereby power is generated by a first power source that operates by burning a fuel. The control device identifies, on the basis of a pressure difference in a prior-stage mechanism that supplies the fuel to the first power source, a fuel capacity that compensates for the pressure difference in the prior-stage mechanism. The pressure difference is the difference between a pressure set for the fuel before a load change in the prior-stage mechanism and a pressure set for the fuel after the load change in the prior-stage mechanism. The control device calculates a fuel supply command value, which is a command value for adjusting the amount of fuel supplied to a fuel supply device that supplies the fuel to the first power source, and is output to the fuel supply device using a fuel supply acceleration command value.
