An LMI Approach to Stability Analysis of PWM DC-DC Buck Converters
arXiv:math/0610664
Abstract
The paper considers a DC-DC buck power converter employing pulse width modulation and voltage feedback control. Global asymptotical stability of a periodical operating mode is examined. It is shown that the stability analysis can be reduced to study of a feasibility problem of semidefinite programming.
