Talk:LMIs in Control/Discrete-Time Algebraic Riccati Inequality (DARE)

Incorrect statements
This page presents completely incorrect results. The left-hand side of the Riccati inequality should negative semidefinite and not positive semidefinite. It is immediate to find examples for which the computed control law does not stabilize the system. The provided code shows that. In this regard, this page should be removed. 2A04:EE41:6:927B:80FF:E28F:B1D3:82A5 (discuss) 09:17, 20 February 2023 (UTC)
