Boost-type dc-dc converters present non-minimum phase dynamic system characteristics. Therefore, controller design using only the output voltage for feedback purposes is not a very straightforward task. Even though control can be achieved inductor current control, implementation of such current-mode controllers may require prior knowledge load resistance and also demand more states as one or cu...

the bulk of research within the interactionist framework seems to be consensually pointing to the beneficial effects of interaction in sla. however, few studies have investigated the role of training in providing and perceiving interactional feedback, especially among young learners. this study probed the effects of training prior to engagement in interaction in case of young learners acquiring...

in this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. it provides both robust tracking and load swing suppression. inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. the crane nonlinearities are then tr...

Abstract This study examined the effect of two types of feedback, post-text as a written feedback and recast as an oral one on written grammatical accuracy of Iranian intermediate EFL learners. To this end, 45 intermediate students who were studying at Ideal Language Institute in Sari were selected based on their performance on the Nelson proficiency test, and then divided into three groups (tw...

In this paper, the operation of a fuzzy predictive filter used to provide high robustness against feedback signal noise in a fuzzy logic (FL)-based angle estimation algorithm for the switched reluctance motor is described. The fuzzy predictive filtering method combines both FL-based time-series prediction, as well as a heuristic knowledge-based algorithm to detect and discard feedback signal er...

In a wind power generator using doubly fed induction generator (DFIG), the three-phase pulse width modulation (PWM) voltage source converter (VSC) is used as grid side converter (GSC) and rotor side converter (RSC). The standard linear control laws proposed for GSC provides not only instablity against comparatively large-signal disturbances, but also the problem of stability due to uncertainty ...
