— We present an axiomatic framework for seeking a distance between power spectral density functions. The axioms require that the sought metric respects the effects of additive and multiplicative noise in reducing our ability to discriminate spectra, as well as the require continuity of statistical quantities with respect to perturbations measured in the(More)
— It is a well-known fact that set-point following, in linear control systems, requires an integrator in the feedback loop. However, such an integrator introduces phase lag which may often have a destabilizing effect. A variety of options exist for adding lead to mediate this effect. In this paper we consider yet another option, a fractional integrator. We(More)

— The parametrization of solutions to scalar interpolation problems with a degree constraint relies on the concept of spectral-zeros –these are the poles of the inverse of a corresponding spectral factor. In fact, under a certain degree constraint, the spectral-zeros are free (modulo a stability requirement) and parameterize all solutions. The subject of(More)
