Current Dynamically Predicting Control of PMSM Targeting the Current Vectors

open access: yesJournal of Electrical Engineering and Technology, 2015
This paper present a current predicting control method for PMSM (permanent magnet synchronous motor) to improve the tracking performance of stator current, which regards the current vector as the control target. Solving the model state equation in the static frame (α-β frame), the dynamic change of current vector will be gained as three independent ...

Hysteresis current control of a vector controlled induction motor and DTC: an assessment

open access: yesInternational Journal of Electronics, 2004
This paper presents the speed control of an induction motor using nonlinear current control in rotating coordinates. Two hysteresis comparators and the position of the motor flux are used to generate directly the gate pulses for the power transistors of the inverter.

How effective is integrated vector management against malaria and lymphatic filariasis where the diseases are transmitted by the same vector? [PDF]

open access: yes, 2014
The opportunity to integrate vector management across multiple vector-borne diseases is particularly plausible for malaria and lymphatic filariasis (LF) control where both diseases are transmitted by the same vector.
