I have a problem with the spacing of my equations. According to this https://tex.stackexchange.com/a/50348/15360 booktabs one should rarely have to regulate the spacing.
But the result of the code below gives me:
\documentclass[a4paper,10pt,twoside]{article}
\usepackage[cmex10]{amsmath}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{floatrow}
\begin{document}
\begin{table}[htb!]
\renewcommand{\arraystretch}{1.2}
\caption{Parameters which Torque logs.}
\label{tbl:2_1_1}
\begin{tabular}{c|c|c}
\toprule
{$\mathbf{q_1/q_2}$} & {$\mathbf{0}$} & {$\mathbf{1}$} \\ \midrule
\multirow{2}{*}{$\mathbf{0}$} &
$\displaystyle\frac{\mathrm{d}v_C}{\mathrm{d}t} =
-\frac{1}{C}I_\mathrm{load}$ &
$\displaystyle\frac{\mathrm{d}v_C}{\mathrm{d}t} =
\frac{1}{C}i_L - \frac{1}{C}I_\mathrm{load}$ \\
&
$\displaystyle\frac{\mathrm{d}i_L}{\mathrm{d}t} =
-\frac{R_L}{L}i_L$ &
$\displaystyle\frac{\mathrm{d}i_L}{\mathrm{d}t} =
-\frac{1}{L}v_C - \frac{R_L}{L}i_L$ \\ \hline
\multirow{2}{*}{$\mathbf{1}$} &
$\displaystyle\frac{\mathrm{d}v_C}{\mathrm{d}t} =
-\frac{R_L}{L}i_L - \frac{1}{L}V_s$ &
$\displaystyle\frac{\mathrm{d}v_C}{\mathrm{d}t} =
\frac{1}{C}i_L - \frac{1}{C}I_\mathrm{load}$ \\
&
$\displaystyle\frac{\mathrm{d}i_L}{\mathrm{d}t} =
-\frac{1}{C}I_\mathrm{load}$ &
$\displaystyle\frac{\mathrm{d}i_L}{\mathrm{d}t} =
-\frac{1}{L}v_L - \frac{R_L}{L}i_L + \frac{1}{L}V_s$ \\ \bottomrule
\end{tabular}
\end{table}
\end{document}
I also used $\begin{aligned} ... \end{aligned}$
for combining the equations such that you don't have to use the \multirow
command.

Playing with arraystretch
or \\[8mm]
didn't help either.
