... Properties of state Transition matrix => 1) $\phi(o)$ = $e^{Ao}$ = I 2) $\phi(t) = e^{At} = [\phi(-t)]^{-1}$ i.e. $\phi^{-1}(t) = \phi(-t)$ 3) $\phi(t_1 + t_2) = e^{A(t_1+t_2)}$ =$e^{At_1}.e^{At_2} = \phi(t_1).\phi(t_2)$ 4) $[\phi(t)]^n = [e^{At}]^n$ = $\phi(nt)$ 5) $\phi(t_2-t_1).\phi(t ... written 6 days ago by Mayank Aggarwal ♦♦ 0 • updated 4 days ago by abhishektiwari1712 ♦♦ 30 0 answers 10 views 0 answers ...
