Cayley-Hamilton Theorem [Control Bootcamp]

Ғылым және технология

Here we describe the Cayley-Hamilton Theorem, which states that every square matrix satisfies its own characteristic equation. This is very useful to prove results related to controllability and observability.
These lectures follow Chapter 8 from:
"Data-Driven Science and Engineering: Machine Learning, Dynamical Systems, and Control" by Brunton and Kutz

    I 've watched about 5 videos of C-H theorem and each of you is explaining it differently.. I think you should all gather together and talk this through..

    C-H is a big theorem that has found it's way into many different applications. Each of these will have a different interpretation based on what it is used for in their field, and the "best interpretation" is usually dependent on context or is whichever melds with your psychology.

    @@spoopedoop3142 The only real interpretation is that you can use the eigenvalues of a matrix to form an interpolation problem. E.g matching on eigenvalues. Find the inverse or any power in terms of the characteristic equation is just a special case of mapping onto analytic functions.

    n here is still the dimentions of the state right? I got pretty confused trying to follow this one, the others have been fantastic so far though. Edit: and alpha is the coefficient of that bit of the characteristic polynomial I think? is there a fancy way to get that without going the long way around and multiplying out A

    I understand that matrix A's order can by lowered Cayley-Hamilton theorem, but what about the alpha term that is multiplied to A. Can the order of t in the alpha term also be reduced by some fascinating theory? Anyway thank you for the lecture sir.

    Emre Yılmaz The C-H theorem is valid for all square matrices, no exceptions. The lecturer was confused by someone who erroneously thought otherwise.

    Of course, the guy is wrong. Someone told him that there are some square matrices that do not satisfy their own characteristic polynomial and he has repeated this false claim. The C-H is a perfect theorem and holds for every matrix (as long as it is a matrix with coefficients in a commutative ring, such as Z, R, C etc.).

    The guy is obviously wrong when claiming that Caley-Hamilton theorem is not true for some matrices (of course he did not present any such counterexample). Every matrix satisfies its characteristic equations provided that its entries are in commutative ring. But this is the case of reals, complex or integer numbers. I do not thing that he may have thought of the matrices with, let’s say, quaternions elements. This is quite a different story - there are even problems with defining a determinant for such non-commutative fields.
