Solution of State Eqs when A matrix is Time dependent

  1. Sep 23, 2009 #1
    Hi all,

    I am struggling to solve some simple state equations in the following form.

    dx/dt = A x + bu

    solution is simple if A has only constant elements, because i can multiply both sides with exp(-At) and solve.

    in my case, A has time dependent elements. i know their functions. is there any particular solution for this case?

    thank you in advance.
