Similar to the first case, the phase response with the proposed method is smoother and faster. The phase overshoot is reduced from 42.8% to 24.7% and the settling time is reduced from 44 to 40 ms, which agree well with the results presented in Table 1.

WebMar 23, 2024 · Stationary phase method for two stationary points. I have a function ψ ( t) which has two stationary points at t = a and t = b and I want to find the asymptotic form of the integral I ( x) = ∫ a b f ( t) e i x ψ ( t) d t. Bender&Orzsag talks about the approximation around a single stationary point, namely the lower limit of the integral ... WebThe idea of phase 1 is to remove the artificial variables from the basis and get the trivial solution for the exthended problem. At this case, we can to pass to phase-two by eliminating artificial vars. We will see in this section an example of the two phase method and how to handle artificial and slack variables. An even more complete is here.
