Abstract
To provide a feedback control device that achieves smooth continuous control at the time of switching of binary feedback controls. When, as a result of constant current feedback control being performed through a connection between a current control unit 12 and an I control unit 24, a detected measured voltage value of a control object 21 reaches a preset value that is maintained by constant voltage feedback control, a u1/u2 determination unit (switching determination unit) 27 controls changeover switches 22 and 23 to connect a voltage control unit 15 and the I control unit 24 and, in addition, connect the voltage control unit 15 to an adder 25 to which the I control unit 24 is connected, and performs switching to constant voltage feedback control.
