Sensorless Control for DC–DC Boost Converter via Generalized Parameter Estimation-Based Observer

Generalized Switched-Inductor Based Buck-Boost Z-H Converter

In this paper, a generalized buck-boost Z-H converter based on switched inductors is proposed. This structure consists of a set of series connected switched-inductor cells. The voltage conversion ratio of the proposed structure is adjusted by changing the number of cells and the duty cycle. Like the conventional Z-H converter, the shoot-through switching state and the diode before LC network ar...

Observer-Side Parameter Estimation For Adaptive Control

of Thesis Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science OBSERVER-SIDE PARAMETER ESTIMATION FOR ADAPTIVE CONTROL By Jason Nezvadovitz August 2017 Chair: Warren Dixon Major: Mechanical Engineering In adaptive control, a controller is precisely designed for a certain model of the system, but that model’s...

Observer-based controller for current mode control of an interleaved boost converter

A state feedback control method for an interleaved boost power converter is designed, which, in turn, can achieve interleaved current sharing among parallel-connected converters. The state feedback control in the continuous time domain is derived using the pole placement technique and linear quadratic optimal method. The load estimator is designed by deriving a full-order state observer to ensu...

Bifurcation Study and Parameter Analyses Boost Converter

This paper deals with bifurcation analyses in current programmed DC/DC Boost converter and exhibition of chaotic behavior. This phenomenon occurs due to variation of a set of the studied circuit parameters (input voltage and a reference current). Two different types of bifurcation paths have been observed as part as part of another bifurcation arising from variation of suitable chosen parameter...
