Analysis of second-order parametric systems with impulse variations
R.K. Keenan, W. A. Brown · Electronics Letters · 1967
A method for handling a second-order differential equation with a coefficient comprised of δfunction plus arbitrary-function terms is given. Application of this method to a sampled-data control system leads to the same results as those which are obtained via Ztransform theory, thus providing a particular-case verification of the method.
