Efficient Jacobian Determination by Structure-Revealing Automatic Differentiation

Xiong, Xin January 2014 (has links)
This thesis is concerned with the efficient computation of Jacobian matrices of nonlinear vector maps using automatic differentiation (AD). Specifically, we propose the use of two directed edge separator methods, the weighted minimum separator and natural order separator methods, to exploit the structure of the computational graph of the nonlinear system.This allows for the efficient determination of the Jacobian matrix using AD software. We will illustrate the promise of this approach with computational experiments.

Spínaný zdroj s digitální řídící smyčkou / Power switch source with digital loop

Zápeca, Jan January 2012 (has links)
The diploma thesis is describing how forward converter works. The diploma thesis presents the function of forward converter with demagnetizing winding and presents the function of two-switched forward converter. The diploma thesis descibes the behaviour of continuous current mode and discontinuous current mode. The diploma thesis explains the reasons for implementation feedback and presents the basic types of compensations. The project deals with AC analysis of two-switched forward converter with continuous peak current mode control. The Analog prototyping metod is used for digital control design. The function of the converter was tested in laboratory. The laboratory results have been compared with the theoretical and the simulation results.
