Reducing the cogging torque effects in hybrid stepper machines by means of resonant controllers
(Institute of Electrical and Electronics Engineers (IEEE), 2018-06-11)
Article
Open AccessPermanent magnet machines are not free from the interaction between magnets and the stator and rotor slots, which causes an undesired disturbing torque. Such cogging or detent torque is especially larger with salient pole ... -
Combined production of electricity and hydrogen from solar energy and its use in the wine sector
(2018)
Article
Open AccessIn the present research, the energy demanded by the wastewater treatment plant of a winery and the pumping station of the irrigation system of a vineyard is supplied by a stand-alone renewable energy system formed by three ... -
Fixed Switching Period Discrete-Time Sliding Mode Current Control of a PMSM
(Institute of Electrical and Electronics Engineers (IEEE), 2017-08-25)
Article
Open AccessA fixed switching period sliding mode control (SMC) for Permanent Magnet Synchronous Machines (PMSMs) is presented. The aim of the paper is to design a SMC that improves the traditional PI based Field Oriented Control (FOC) ... -
Sensorless control strategy for light-duty EVs and efficiency loss evaluation of high frequency injection under standardized urban driving cycles
(2018-08-15)
Article
Restricted access - publisher's policySensorless control of Electric Vehicle (EV) drives is considered to be an effective approach to improve system reliability and to reduce component costs. In this paper, relevant aspects relating to the sensorless operation ... -

Effect of metal hydride properties in hydrogen absorption through 2D-axisymmetric modeling and experimental testing in storage canisters
(2017-07-27)
Article
Open AccessA two-dimensional axisymmetric model is developed to study the hydrogen absorption reaction and resultant mass and heat transport phenomena inside a metal hydride canister. The model is compared against published literature ... -
On Existence of equilibria of multi-port linear AC networks with constant-power loads
(2017-10-01)
Article
Open AccessThis paper explores the problem of stability of linear time-invariant (LTI), multi-port AC circuits with instantaneous constant-power loads (CPLs), which model the behavior of some point-of-load converters. It is well-known ... -
Analysis of the dynamics of an active control of the surface potential in metal oxide gas sensors
(Pergamon Press, 2018-05-08)
Article

An Interactive and comprehensive software tool to promote active learning in the Loop Shaping Control System design
(Institute of Electrical and Electronics Engineers (IEEE), 2017-06-07)
Article
Open AccessThe classical loop shaping is a design procedure that explicitly involves the shaping of the open loop transfer function L(s), within a desired frequency spectrum by manipulating the poles, zeros, and gain of the controller ... -
A new approach for flux and rotor resistance estimation of induction motors
(2017-07-01)
Article
Restricted access - publisher's policyIn this paper we address the problems of flux and rotor resistance estimation of induction motors. We propose a radically new approach that combines the recently introduced techniques of parameter estimation based observers ... -
On average real sliding dynamics in linear systems
(2017-07-01)
Article
Open AccessIt is well known that in implementations of sliding mode controllers using hysteresis comparators, when the hysteresis band amplitude tends to zero the real dynamics tends to the ideal sliding dynamics. However, in real ...
