Correction to "High Performance Digital Resonant Controllers Implemented With Two Integrators" [Feb 11 563-576]

In the above titled paper (ibid., vol. 26, no. 2, pp. 563-576, Feb. 2011), there were errors in Figs. 3 and 9. The correct figures are presented here. Note that now the adder signs in the resonant poles correction are not always positive, as they were in the original paper, but alternatively positive and negative, in accordance to (9) from this paper, which is reproduced here.
