چکیده
We derive a simple accuracy matching strategy for inexact Gauss Newton methods and apply it to the numerical solution of boundary value problems of ordinary diierential equations by collocation. The matching strategy is based on an aane contravariant convergence theorem, i.e., the characteristic constants are invariant under aane transformations of the domain. The inexact Gauss Newton method is applied to an integral formulation of the BVP. As discretization for the arising linear subproblems we employ adaptive collocation at Gaussian nodes with varying local orders and stepsizes. The grids are chosen via adaptive reenement and order selection.

FPGA Implementation of Selective Harmonic Elimination Controlled Asymmetrical Cascaded Nine Levels Inverter Using Newton Raphson Algorithm
Asymmetrical structure is used to reduce the number of bridges and gate drive circuits and DC sources. This structure therefore provides the capability to produce higher voltages at higher speeds with low switching frequency which has inherent low switching losses and high converter efficiency. Newton Raphson (N-R) algorithm is investigated for the selective harmonic elimination (SHE) to calcul...

متن کاملAnalysis of a Multilevel Iterative Method for Nonlinear Finite Element Equations
The multilevel iterative technique is a powerful technique for solving systems of equations associated with discretized partial diierential equations. We describe how this techniques can be combined with a globally con-vergent approximate Newton method to solve nonlinear partial diierential equations. We show that asymptotically only one Newton iteration per level is required; thus the complexi...
متن کاملMultilevel Gauss–Newton Methods for Phase Retrieval Problems
The phase retrieval problem is of wide interest because it appears in a number of interesting application areas in physics. Several kinds of phase retrieval problems appeared in laser optics over the past decade. In this paper we consider the numerical solution of two phase retrieval problems for an unknown smooth function f with compact support. We approximate f by a linear spline. The corresp...
متن کاملA Multilevel Method for Image Registration
In this paper we introduce a new framework for image registration. Our formulation is based on consistent discretization of the optimization problem coupled with a multigrid solution of the linear system which evolve in a Gauss-Newton iteration. We show that our discretization is h-elliptic independent of parameter choice and therefore a simple multigrid implementation can be used. To overcome ...
