Claim:
1. A power control device, comprising: a control circuit configured to control a power source; and a control calculation unit configured to calculate a manipulation amount by which the control circuit controls the power source, the control calculation unit comprising: wherein the control circuit comprises a switch configured to switch application of at least one of the predetermined parameters, wherein the switching control unit is further configured to apply at least one of the predetermined parameters by turning on the switch based on the determination that the first disturbance has occurred or the determination that the second disturbance has occurred, and wherein when the reference value difference is E1(t), the lapse difference is E2(t), parameters K0, K1, K2, and K3 are the predetermined parameters, the manipulation amount is U(t), the manipulation amount before one control period is U0(t−1), and the reference value difference before one control period is E1(t−1), the switch has a first switch configured to switch application of the parameter K2 in Eq. (1) set forth below, and a second switch configured to switch application of the parameter K3 in Eq. (1), when an absolute value of the reference value difference calculated by the difference calculation unit exceeds a predetermined voltage threshold value, the determining unit determines that the first disturbance has occurred, and when an absolute value of the lapse difference calculated by the difference calculation unit exceeds the predetermined voltage threshold value, the determining unit determines that the second disturbance has occurred, and when it is determined by the determining unit that the first disturbance has been detected, the switching control unit applies the parameter K3 by turning on the second switch, and when it is determined by the determining unit that the second disturbance has been detected, the switching control unit applies the parameter K2 by turning on the first switch and simultaneously applies the parameter K3 by turning on the second switch.
