Talk:Algebraic Riccati equation

Description of the coefficient matrices

It would be nice to have a brief description of what Q and R are. In the case of LQG and LQR control it might be obvious, but there are other areas where the Riccati equation is used. 195.176.110.69 (talk) 14:56, 14 April 2014 (UTC)[reply]

Both initialisms are now defined in the article. Re Stacks (talk) 23:32, 28 October 2024 (UTC)[reply]

Consistency with notation

Why, when mentioning ${\dot {x}}(t)=A_{t-1}x_{t-1}+B_{t-1}u_{t-1}$ , why are we using $t$ when in most control material, discrete time is denoted as $k$ ? Barcodenumber (talk) 18:52, 20 October 2024 (UTC)[reply]
