Accés restringit per política de l'editorialThis paper presents a sliding mode controller for a narrow tilting three-wheeled vehicle. The vehicle is modelled as a dynamic eighteen-order system with two inputs and two outputs, however, a simple third-order model of ... -
A stator voltage oriented PI controller for the doubly-fed induction machine
(Institute of Electrical and Electronics Engineers, 2007)
Text en actes de congrés
Accés obertIn this paper we propose a new control scheme for the doubly–fed induction machine (DFIM) that offers significant advantages, and is considerably simpler, than the classical vector control method. In contrast with the ... -
A survey of repetitive control in varying frequency conditions
(2011-08)
Article
Accés obertDigital repetitive control is a strategy that allows tracking/ rejecting periodic signals. Repetitive controllers are designed assuming that the exogenous signal period is constant and known, its main drawback being the ... -
A transient model for RF cavity analysis under beam loading
(2010-04)
Article
Accés restringit per política de l'editorialThere are two important considerations in the development of an electrical model for RF cavities to be used for system analysis or LLRF loop design, being: transient response and cavity impedance mismatch. In the literature, ... -
A unified approach to explain contrary effects of hysteresis and smoothing in nonsmooth systems
(2017-09-01)
Article
Accés obertPiecewise smooth dynamical systems make use of discontinuities to model switching between regions of smooth evolution. This introduces an ambiguity in prescribing dynamics at the discontinuity: should the dynamics be given ... -
