Doppler sensing aided HEMP waveform parameter estimation [PDF]

open access: yesJournal of Hebei University of Science and Technology
Aiming at the problem of significant Doppler frequency shift (DFS) in the waveform of high altitude electromagnetic pulse (HEMP) emitted by aircraft moving at high speed, which severely reduces the accuracy of HEMP waveform parameter estimation, a method

Self-adaptive stepsize affine projection based parameter estimation of IPMSM using square-wave current injection

open access: yesCES Transactions on Electrical Machines and Systems, 2017
Affine projection algorithm (APA) has been used to estimate the parameters of interior permanent magnet synchronous motor (IPMSM). However, there is not a strict guideline of choosing the stepsize of this algorithm to make sure that the results of ...

The parameter estimation algorithms based on the dynamical response measurement data

open access: yes, 2017
This article studies the parameter estimation to the system response from the discrete measurement data. By constructing the dynamical rolling cost functions and using the nonlinear optimization, the gradient identification method is presented for ...

Comparison of estimation limits for quantum two-parameter estimation

open access: yesPhysical Review Research
Measurement estimation bounds for local quantum multiparameter estimation, which provide lower bounds on possible measurement uncertainties, have so far been formulated in two ways: by extending the classical Cramér-Rao bound (e.g., the quantum Cramér ...

Parameter estimation for alpha-fractional bridges

open access: yes, 2013
Let alpha,T>0. We study the asymptotic properties of a least squares estimator for the parameter alpha of a fractional bridge defined as dX_t=-alpha*X_t/(T-t)dt+dB_t, with t in [0,T) and where B is a fractional Brownian motion of Hurst index H>1/2 ...
