    • PROBLEM TO BE SOLVED: To provide a feedback control method, a feedback control device and a feedback control program for increasing followability to a target value by avoiding the saturation of manipulated variables.SOLUTION: A feedback control method for determining manipulated variables to be output to a control target such that an observation amount to be acquired from a control target is coincident with a target value includes: a step 150 of filtering the target value by using a filter having low-pass specification; a step 160 of determining the manipulated variables in accordance with a deviation between the filtered target value and the observation amount; and a step 190 of delaying the change speed of the filtered target value in accordance with at least either the fact that the target value has been changed or the fact that the determined manipulated variables have deviated from a predetermined allowable range or approached the allowable range.

    • A control unit of a system stabilizing device uses a fluctuation detecting block 200 for determining current commands from a system current. A fluctuation detecting unit 300 determines, from an active component Isd of the system current, a common current command Irefd0 which is a fluctuation component of the active component Isd. A first current command creating unit 400 receives as an input the current command Irefd0, and outputs a current command Irefd1 whose signal width is as small as T4 and which instantaneously rises and then gradually decreases. A second current command creating unit 500 receives as an input the current command Irefd0, and outputs a current command Irefd2 which gradually increases for a time T4 and then gradually decreases for a time (T3-T4). The system stabilizing device having short charging and discharging times is controlled by the current command Irefd1, while the system stabilizing device having long charging and discharging times is controlled by the current command Irefd2, whereby system stabilizing controls can be exercised without interferences. In this manner, even if system stabilizing devices having different charging and discharging characteristics are provided, system stabilizing controls can be effected without interferences.
