Determine the preferred multiloop control strategy for a process with the following steady-state gain matrix, which has been scaled by dividing the process variables by their maximum values:
\left [ \begin{matrix} y_{1} \\ y_{2} \\ y_{3} \end{matrix} \right ] = \left [ \begin{matrix} 0.48 & 0.90 & -0.006 \\ 0.52 & 0.95 & 0.008 \\ 0.90 & -0.95 & 0.020 \end{matrix} \right ]\left [ \begin{matrix} u_{1} \\ u_{2} \\ u_{3} \end{matrix} \right ] (18-69)
