Talk:Full state feedback

Some of the LaTeX commands I have used in my article on Full State Feedback (FSF) are not recognized by the Wikipedia math environment. Does anybody know how to write matrices or vector arrays in the math environment on Wikipedia?

Determinant in characteristic equations?
The first characteristic equation is defined using |something|, whereas the second is det|something|. I think only one is right. 37.44.138.159 (talk) 11:24, 11 October 2018 (UTC)

Hmm. It appears using the determinant is right, but also that |something| sometimes denotes the determinant of something. Nevertheless, the notation should have been consistent. I will leave to experts to choose a correct one, although I personally would prefer det(something).37.44.138.159 (talk) 11:32, 11 October 2018 (UTC)

Feedback with integrator and design in discrete time.
It is possible to design the feedback with an integrator Ki as well, which is not mentioned in this article. It is also possible to design state feedback directly within a discrete-time system. Should these possibilities be added? I have no experience with editing articles, or what contents they should have. SebR ECE (talk) 09:07, 31 May 2021 (UTC)
