Control system for controlling individual harmonic current of filter

The invention refers to the relative technical field of filters, in particular to a control system for controlling individual harmonic current of a filter. A control system for controlling individual harmonic current time of the filter comprises a repetitive controller and a filter which are orderly connected; the output of the repetitive controller is connected with the input of the filter; the individual harmonic current of the filter is accessed to the input end of the repetitive controller via a negative feedback. In the invention, a repetitive controller is used for controlling, such that the difficulty in controlling is lightened and the algorithm is simple; the control system for controlling individual harmonic current of filter can realize the advanced action control and has excellent steady state performance.
