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 ...

The class of second-order linear dynamical systems is considered. A method and algorithm are presented to transform any system with n degrees of freedom into n independent second-order equations. The ...

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 ...
