in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

Recent studies on human motor control have been largely innuenced by two important statements: (1) Sensory feedback is too slow to be involved at least in fast motor control actions; (2) Learned internal model of the systems plays an important role in motor control. As a result , the human motor control system is often described as open-loop and particularly as a system inverse. System inverse ...

introduction: feedback cards are recommended as a feasible tool for structured written feedback delivery in clinical education while effectiveness of this tool on the medical students’ performance is still questionable. the purpose of this study was to compare the effects of structured written feedback by cards as well as verbal feedback versus verbal feedback alone on the clinical performance ...

L2 written corrective feedback has been investigated from different perspectives in SLA research (e.g. Ahmadian & Tajabadi, 2015; Bitchener & Knoch, 2010; Ferris, 2006). Taking the cognitive and sociocultural paradigms into account, the aims of the current study are twofold: Firstly, it attempts to find if corrective feedback is effective in improving the linguistic accuracy of L2 learners' ten...

in this paper the active vibration control of a four-story shear frame instrumented with piezoelectric actuators is presented. the piezoelectric actuators are hosted on the columns in two manners and the produced controlling forces by actuators are considered in the equation of motion. the smart structure modeling and control design is carried out using matlab software in state space form. subs...
