Minimal Positive Realizations of Transfer Functions with Positive Real Poles
A standard result of linear-system theory states that a SISO rational th-order transfer function always has an th-order realization. In some applications, one is interested in having a realization with nonnegative entries (i.e., a positive system) and it is known that a positive system may not be minimal in the usual sense. In this paper, we give an explicit necessary and sufficient condition f...
متن کاملMinimal discrete - time positive realizations of transfer functionswith positive real polesLuca
A standard result of linear system theory states that a SISO rational n-th order transfer function always has a n-th order realization. In some applications one is interested in having a realization with nonnegative entries (i.e. a positive system). In this paper we give a contribution to the discrete-time realization problem by providing explicit necessary and suucient conditions for a third o...
متن کاملMinimal eventually positive realizations of externally positive systems
It is a well-know fact that externally positive linear systems may fail to have a minimal positive realization. In order to investigate these cases, we introduce the notion of minimal eventually positive realization, for which the state update matrix becomes positive after a certain power. Eventually positive realizations capture the idea that in the impulse response of an externally positive s...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولLattice Realizations of Unitary Minimal Modular Invariant Partition Functions
The conformal spectra of the critical dilute A–D–E lattice models are studied numerically. The results strongly indicate that, in branches 1 and 2, these models provide realizations of the complete A–D–E classification of unitary minimal modular invariant partition functions given by Cappelli, Itzykson and Zuber. In branches 3 and 4 the results indicate that the modular invariant partition func...
