polezero 
Optimal approximation of headrelated transfer function's polezero model based on genetic algorithm


The controller design depends on the specific polezero patterns.


In practice, the polezero patterns remain the same, no matter how the physical system parameters are different.


Using a polar coordinate based polezero representation, two different lowpass filter design problems are explored.


For exact polezero cancellation, we consider the dynamics of power amplifier used for actuator current regulation and the effects of delay in control action.


Polezero extraction by nonlinear regression of discretetime arterial bloodflow waveforms


For polezero modelling using the SteiglitzMcBride method with maximum entropy and extrapolation to zero, the optimum values are 14 poles and 14 zeros.


In contrast to the currently popular minimumenergy approach, which has limited spectral resolution and is sensitive to noise, high spectral resolution is possible with the rational model because of its polezero nature.


We consider one such biquad proposed over a decade ago by David and coworkers and show its equivalence to two other formulations in terms of their polezero pair locations in thezplane.


Excitation is used only initially to avoid polezero cancellation of the parameter estimates.


The orthotropic properties of the passive tissue are described here by a "polezero" constitutive law, whose parameters are derived in part from a model of the underlying distributions of collagen fibres.


The resonant lowpass filter application demonstrates that analog transfer functions with bounded spectrums can be converted to accurate digital spectrum counterparts without polezero decompositions.


Decoupling and polezero assignment of singular systems with dynamic state feedback


Finally a method is presented for polezero placement in the decoupled singular system and a structure is described for the realization of the generalized transfer function matrices.


Infinite elementary divisors of general polynomial matrices are defined and their relation to the polezero structure of polynomial matrices at infinity is examined.


1997, a new adaptive algorithm for constrained polezero notch filters is derived using the SteiglitzMcBride adaptive scheme and a normal statespace realization.


Though both the proposed and the normalized latticebased structures are BIBO stable, the former is simpler and, more interestingly, has minimal polezero sensitivities.


The fractional power factor which parametrizes the FPP or the DavidsonCole function has been shown earlier to equal the logarithmic ratio of the locations of the polezero singularities.


The method is then applied to decompose the ColeCole function; the polezero placement of the singularity function is determined and the equivalent cascadeRC network is synthesized.


Allpole and polezero models for the vocal tract are developed.
