Abstract:
First we determine necessary and for some cases also sufficient
conditions for a polynomial to be the characteristic polynomial of a
matrix with elements in Rmax. Then we indicate how to
construct a matrix such that its characteristic polynomial is equal to
a given monic polynomial in Smax, the extension of
Rmax. Next we use these results to develop a procedure to
find the minimal state space realization of a single input single
output (SISO) discrete event system, given its Markov parameters.
