An algorithm for the construction of nonnegative realizations

We present an effective method for the construction of a nonnegative realization of a real coefficient scalar transfer function having a single dominant (positive) pole and complex poles within the spectral disc, all of arbitrary orders. The nonnegativity of the impulse response is not assumed, but...

Tartalmi kivonat:We present an effective method for the construction of a nonnegative realization of a real coefficient scalar transfer function having a single dominant (positive) pole and complex poles within the spectral disc, all of arbitrary orders. The nonnegativity of the impulse response is not assumed, but the nonnegativity of the coefficients of the dominant terms in the partial fraction decomposition of the transfer function. If a coefficient in this decomposition is sufficiently large, then a general realization algorithm is applicable with a priori estimation of the dimension of the obtained nonnegative realization. An example shows the practical application of the realization process.
