Hi all,
I would like to know if there’s someone can help me with this question:
If the following
\left[ {\begin{array}{*{20}{c}} {{A^T}P + {K^T}{B^T}P + PA + PBK + C_z^T{C_z}}&{P{B_w}} \\ {B_w^TP}&{ - \gamma } \end{array}} \right] \prec 0
is equivalent to (by schur complement)
\left[ {\begin{array}{*{20}{c}} {{A^T}P + {K^T}{B^T}P + PA + PBK}&{C_z^T}&{P{B_w}} \\ {{C_z}}&{ - 1}&0 \\ {B_w^TP}&0&{ - \gamma } \end{array}} \right] \prec 0
Thank you very much in advance.
Kind regards,
Lam
