In this paper, hybrid pulse width modulation algorithm for vector controlled induction motor drives is used to reduce the steady state ripple in current. Also the newly developed Hybrid PWM technique does not use angle and sector information and hence it simplifies the control algorithm. The conventional Space vector pulse width modulation (CSVPWM) algorithm gives inferior performance at higher...

The direct torque control provides precise and quick response and the SVPWM algorithm gives good performance for control of induction motor drive, but these algorithms produces more acoustical noise resulting in increased distortion of harmonics. To reduce these effects various PWM techniques were used in recent. Though the deterministic pulse width modulation (PWM) algorithms give good perform...

Human subjects performed step-tracking movements of the wrist in the radial direction. Movement amplitude, external load, and accuracy instructions were varied. We used surface electrodes to record muscle activity from an agonist, extensor carpi radialis longus, and an antagonist, extensor carpi ulnaris. When subjects performed movements “as fast as possible” that were opposed by different exte...

We study zigzag graphene nanoribbons with periodic edge roughness and report significant band gap opening. Interestingly, such nanoribbons have a near-midgap state with a small band width. We extensively study the electronic structure and the electric-field modulation of the conduction/valence bands and the near-midgap state. We summarize the important electronic-structure features like the ban...
