Controller of fan coupling device

A controller of a fan coupling device includes: an acquisition unit that acquires an acceleration parameter and a deviation parameter; a control unit that controls a regulation mechanism; a prediction unit that predicts that hunting occurs in the rotation speed of the fan, when an operating point of...

Beschreibung
Zusammenfassung:	A controller of a fan coupling device includes: an acquisition unit that acquires an acceleration parameter and a deviation parameter; a control unit that controls a regulation mechanism; a prediction unit that predicts that hunting occurs in the rotation speed of the fan, when an operating point of the fan expressed with the deviation parameter and the acceleration parameter belongs to a predicted region; and a restraining unit that executes, when the hunting is predicted to occur, a hunting restraining process of executing at least one of lowering an integral gain of a feedback control to be lower than when the hunting is not predicted to occur and increasing a derivative gain of the feedback control to be higher than when the hunting is not predicted to occur.
