New Space Vector Selection Scheme for VSI Supplied Dual Three-Phase Induction Machine

Abstract: This paper presents a novel space vector selection scheme applicable for the control of dual three-phase induction motor drives supplied from a six-phase voltage source inverter (VSI). The vector selection method is based on the vector space decomposition technique (VSD). Unique vector selection pattern simplifies problems related to complicated implementation of standard VSD in commercially available digital signals processors (DSP). The proposed vector selection scheme is verified through a theoretical analysis, computer simulations and practical experimental results conducted on a dual three-phase test rig prototype with control algorithm implemented in Texas Instrument?s TMS320F2808 DSP.

Abstract: a quantification and comparison among use values of trees in western colombian amazonia is presented. applicability and usefulness of available methods for use value quantification are discussed. we concluded that use value is limited in the expression of real species usefulness and their importance for communities, and also is of limited usefulness as a tool to prioritize species or areas for conservation and some standardization and adaptation of this method is suggested.
