Received Sep 19, 2017 Revised Oct 27, 2017 Accepted Nov 11, 2017 This paper present steady state and dynamic (Transient) models of the doubly fed induction generator connected to grid. The steady state model of the DFIAG (Doubly Fed Asynchronous induction Generator) has been constructed by referring all the rotor quantities to stator side. With the help of MATLAB programming simulation results ...

This paper presents sensorless rotor position estimation of Switched Reluctance Motor (SRM) where the position is to be determined by Adaptive Neuro Fuzzy Inference System (ANFIS). The rotor position sensing is very essential for the SRM for its efficient operation. Previously rotor position sensors are used to estimate the position of rotor for SRM. Due to its drawback the sensors have to be r...

The main purpose of this paper is concerned with the sensitivity analysis of main rotor dynamic response pertaining to variation of some relevant system parameters effectively supports the preliminary design of both articulated and hingeless helicopter rotor configurations. The methodology is laid out based on Galerkin solution of partial differential equation (PDE) of main rotor with flexible ...

This paper describes the comparison of Artificial Intelligence (AI) based rotor position estimation techniques for Switched Reluctance Motor (SRM) with respect to its execution time in Digital Signal Processor (DSP) TMS320F2812. The various networks of Artificial Neural Network (ANN) and Adaptive Neuro Fuzzy Inference System ( ANFIS) structures are trained for mapping the nonlinear current-flux...

by Junye Wang A computational study is carried out to investigate the noise generated by a ten-bladed rotor ingesting low-Mach-number turbulent flow. Two types of turbulent inflows are considered: homogeneous and isotropic turbulence mimicking gridgenerated turbulence in a previous experiment and a turbulent cylinder wake. A hybrid computational approach combining LES with Lighthill’s aeroacous...

This is an introduction to elementary decoherence theory as it is typically applied to superconducting qubits. Abbreviations: SQUID – superconducting quantum interference device; qubit – quantum bit; TSS – two state system

The effects of variation of blade torsion frequency on rotor performance and structural loads are investigated for a 1/rev active flap rotor and baseline rotor (no active control). The UH-60A four-bladed articulated main rotor is studied at a high-speed forward flight condition. The torsion frequencies are varied by modifying the spanwise torsional stiffness of the blade and/or the pitch link s...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...
