WebThis manuscript addresses a novel output model predictive controller design for a representative model of continuous stirred-tank reactor (CSTR) and axial dispersion reactor with recycle. The underlying model takes the form of ODE-PDE in series and it is operated at an unstable point. The model predictive controller (MPC) design is explored to achieve … WebA novel class of high-order Runge–Kutta structure-preserving methods for the coupled nonlinear Schrödinger–KdV equations is proposed and analyzed. With the aid of the quadratic auxiliary variable, an equivalent system is obtained from the original problem.

WebApr 20, 2015 · 1 Answer Sorted by: 8 If you derive the first equation, you get: X " = a X ′ + b Y ′ (if you are considering a and b as constants). But we have Y ′ = c X + d Y, so substitute in the above equation, you get X " = a X ′ + b ( c X + d Y). Note that Y = 1 b ( X ′ − a X) for b ≠ 0 . So, substituting again you get the final answer.
