A second-order system is one which can be described by a second-order differential equation. The files listed below are a combination of PDF tutorial documents, MATLAB Graphical User Interfaces (GUIs) ...
In the previous article, I showed how to compensate simple first-order systems. As a quick recap, a Proportional-Integral (PI) controller is all that is needed for compensating first-order systems ...
An important characterization of a numerical method for first order ODE's is the region of absolute stability. If all eigenvalues of the linear problem y' = Ay are inside this region, the numerical ...
SIAM Journal on Numerical Analysis, Vol. 50, No. 3 (2012), pp. 1604-1623 (20 pages) Decoupling a fourth order elliptic boundary value problem into a system of second order equations may give an ...
