Stator resistance estimation using ANN in DTC IM drives
Induction machine direct torque control (DTC) artificial neural network stator resistance estimation
2010/3/17
Torque control of induction motors (IM) requires accurate estimation of the flux in the motor. But the flux estimate, when estimated from the stator circuit variables, is highly dependent on the stato...
Effects of Epibrassinolide and Abscisic Acid on Sorghum Plants Growing under Soil Water Deficit : II. Physiological basis for drought resistance induced by exogenous epibrassinolide and abscisic acid
Abscisic acid Brassinolide Cuticular transpiration Drought resistance Sorghum Stomatal transpiration
2009/7/31
It was reported that pretreatment with abscisic acid (ABA) increased the drought resistance of sorghum plants and that 22R, 23R epibrassinolide (EBR) enhanced the effects of ABA. To explore the mecha...
