The authors wish to make the following corrections to this paper [] due to an accidental mistake when uploading the last manuscript:

On page 6, Equation (17) should be changed from:

\frac{d δ}{d t} = \frac{d θ_{c}}{d t} - \frac{d θ_{p}}{d t} = \frac{| {u^{'}}_{c s}^{α β} | \sin θ_{u s}}{| {ψ^{'}}_{c s}^{α β} |} - [ω_{p} - (p_{p} + p_{c}) ω_{r}]

(17)

To the following correct version:

{u^{'}}_{c s}^{α β} = \frac{2}{3} V_{b u s} e^{j (π / 3 (n - 1))}

(17)

The authors would like to apologize for any inconvenience caused to the readers due to this mistake and the subsequent changes.
