Considering static behavior of the capacitive element in a reduced model:

\begin{equation}
	\left\{
	\begin{array}{l}
		i_{d} =  - \omega C v_{q} + \displaystyle \frac{1}{R}v_{d} \\ \ \\
		i_{q} =  \omega C v_{d} + \displaystyle \frac{1}{R}v_{q}
	\end{array} 
	\right.
	\rightarrow 
   \begin{bmatrix}
	    i_d \\ 
        i_q
   \end{bmatrix}
   =
   \begin{bmatrix}
	    1/R & -\omega C \\
	    \omega C & 1/R
