LMIs in Control/pages/LMI for Mixed H2 Hinf Output Feedback Control

The System
The objective is to minimize the combined $$ H_{2} $$ and $$ H_{\infty} $$ norms of the closed-loop system.

The LMI: LMI for mixed $$H_{2}/H_{\infty}$$
$$ \begin{align} \text{min} \; \quad t:&\\ \end{align} $$
 * S(P,K) ||_{H_{2}}^{2} + || S(P,K) ||_{H_{\infty}}^{2}
