Nonlinear Control of a Buck Converter Which Feeds a Constant Power Load

IEEE transactions on power electronics, 2015
In this paper, a nonlinear control strategy for controlling a dc/dc buck converter feeding a constant power load is proposed. The main objective of the proposed controller is to improve the transient performance when in presence of unknown power ...

Suppression of Base Excitation of Rotors on Magnetic Bearings

International Journal of Rotating Machinery, 2007
This paper deals with rotor systems that suffer harmonic base excitation when supported on magnetic bearings. Magnetic bearings using conventional control techniques perform poorly in such situations mainly due to their highly nonlinear characteristics ...

Similarity solution for flow over an unsteady nonlinearly stretching rotating disk

AIP Advances, 2015
The unsteady laminar flow of an incompressible viscous fluid over a nonlinearly stretching rotating disk is investigated. The axisymmetric three-dimensional boundary layer equations are reduced into self-similar form with the help of new similarity ...

A novel modeling method for forward-flyback converter and investigating proper design with guidelines to eliminate right half plane zeros [PDF]

AUT Journal of Electrical Engineering
The main advantages of the flyback converter are the simple topology and the isolation of the output from the primary, which is useful for cases where a compact design is required.

Controllability and nonlinearity [PDF]

ESAIM: Proceedings, 2008
We present here three methods (return method, quasi-static deformations, power series expansions) to get controllability results for control systems modeled by partial differential equations when the linearized control system around the equilibrium is not controllable.
