Beschreibung
Zusammenfassung:	A control device includes: a variation command unit that changes a command value, which is a command value sent to a system including a compressor, affecting an operating state of the compressor; a proportional coefficient calculation unit that calculates a proportional coefficient of a variation in a parameter, which indicates a state of the compressor or an electric motor that drives the compressor when the system is operated based on the command value, with respect to the command value; and a control unit that performs control for avoiding or suppressing surging in the compressor, based on a value of the proportional coefficient.
