pole-zero
Optimal approximation of head-related transfer function's pole-zero model based on genetic algorithm
      
The controller design depends on the specific pole-zero patterns.
      
In practice, the pole-zero patterns remain the same, no matter how the physical system parameters are different.
      
Using a polar coordinate based pole-zero representation, two different lowpass filter design problems are explored.
      
For exact pole-zero cancellation, we consider the dynamics of power amplifier used for actuator current regulation and the effects of delay in control action.
      
Pole-zero extraction by nonlinear regression of discrete-time arterial blood-flow waveforms
      
For pole-zero modelling using the Steiglitz-McBride method with maximum entropy and extrapolation to zero, the optimum values are 14 poles and 14 zeros.
      
In contrast to the currently popular minimum-energy approach, which has limited spectral resolution and is sensitive to noise, high spectral resolution is possible with the rational model because of its pole-zero 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 pole-zero pair locations in thez-plane.
      
Excitation is used only initially to avoid pole-zero cancellation of the parameter estimates.
      
The orthotropic properties of the passive tissue are described here by a "pole-zero" constitutive law, whose parameters are derived in part from a model of the underlying distributions of collagen fibres.
      
The resonant low-pass filter application demonstrates that analog transfer functions with bounded spectrums can be converted to accurate digital spectrum counterparts without pole-zero decompositions.
      
Decoupling and pole-zero assignment of singular systems with dynamic state feedback
      
Finally a method is presented for pole-zero 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 pole-zero structure of polynomial matrices at infinity is examined.
      
1997, a new adaptive algorithm for constrained pole-zero notch filters is derived using the Steiglitz-McBride adaptive scheme and a normal state-space realization.
      
Though both the proposed and the normalized lattice-based structures are BIBO stable, the former is simpler and, more interestingly, has minimal pole-zero sensitivities.
      
The fractional power factor which parametrizes the FPP or the Davidson-Cole function has been shown earlier to equal the logarithmic ratio of the locations of the pole-zero singularities.
      
The method is then applied to decompose the Cole-Cole function; the pole-zero placement of the singularity function is determined and the equivalent cascadeR-C network is synthesized.
      
All-pole and pole-zero models for the vocal tract are developed.
