On the discretization of singular systems

N. P. Karampetakis1

1 Department of Mathematics, Aristotle University of Thessaloniki, Greece

This note proposes two new discretization methods. The proposed sampled systems are described in terms of the Markov parameters of the system and therefore the proposed methods are easily implemented. The methodology we use is a zero-order hold discretization for the input and first-order approximation of its derivatives.

Keywords: discretization; singular systems; implicit systems; sampled systems; zero-order hold; first-order hold; Markov parameters.
