This paper describes MATLAB/Simulink implementation of optimal excitation control on a three-phase induction motor (IM) for energy conservation at light loads. This simulation model is developed to support and enhance Loss Minimization Control (LMC) on electric machinery education at the undergraduate and postgraduate level in electrical engineering. This study provides the saving of real, reactive...
This paper presents the speed control scheme of VSI fed indirect vector controlled induction motor (IM) drive. SVPWM technique is used to operate the proposed IM drive. The dynamic performance of drive system is compared with Neural Controller and DSP implemented PI controller in speed feedback loop. Decoupling of the stator current into torque and flux producing (d-q) current components model of...
Now a day's Brushless DC motor (BLDC) and DC motors are being used in most of the Electrical Vehicle. Switched Reluctance Motor (SRM) may become best alternative to BLDS and DC motor in this area because of its constant power output capability, good thermal management and fault tolerance capability. Furthermore SRM having advantages of low weight, high efficiency, small size, low cost and high torque...
We present a quantum transport simulation of tunneling based spin torque transfer (STT) devices using the non equilibrium Green's function (NEGF) formalism in the ballistic regime. We show that it is possible to achieve a quantitative agreement for both the tunneling magneto resistance (TMR) and the amplitude of the switching current with the same set of parameters. We also analyze the device performance...
