How to solve an LMI #981

|
Dear Johan, Hello Here I have an LMI which I do not know how to solve it Is there any sample code that I can study and learn how to deal with it? Here both P>=0 and lambda are unknown and Pi >=0 matrices are tunable. I would be so thankful if you guide me, please. Thanks in advance.

It's not an LMI as you have unsymmetric terms. Your derivation of that condition is severely wrong. I think we have discussed that already elsewhere. |

Dear Johan yes sorry, it seems I made a typing latex error. The right format is as follow |

It's still massively unsymmetric |

Thank u so much here P is symmetric. Is there a text or reference that can help me? |

PB-Pi_4, Psi_1, Psi_2 etc are not symmetric I can only recommend you to read any introductory text on LMIs and semidefinite programming, in particular its use in control as you've completely messed up your stability proof https://web.stanford.edu/~boyd/lmibook/lmibook.pdf |
