| Abstract |
The resonant controller has been proven effective for
AC input current control in the stationary reference frame. In
this paper, we introduce a new type of resonant element.
Associating this element in series or in parallel, we can creat the
resonant controller for multiple frequencies. By using the pole
assignment theory, the design of multi-frequency resonant
controller becomes easier than that by frequency domain
analysis. A criterion polynomial for this approach is given by this
paper, with which the designed controller is efficient and robust
to the variation of system parameters. The digital realization of
the resonant controller is also discussed, and by recalculating
coefficients according to the input frequencies, it can perfectly
regulate the AC input with variable frequencies. The validity and
effectiveness of the proposed approach are verified by simulation
and experimental studies. |
