This example shows the machine load flow tool of powergui block to initialize an induction motor/diesel-generator system open model performance of three pss for interarea oscillations. This thesis describes the development of the torque control algorithm for a permanent magnet brushless dc (pm-bldc) machine used as a starter/generator in a hybrid electric vehicle. Control system design as well as the considerations on the choice of supply device and controller subsystems are jointed in the thesis for final receiving of the design tool for considered industrial drive system. Direct torque control (dtc) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three-phase ac electric motorsthis involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor.

Simpliﬁed modelling and control of a synchronous machine with variable-speed six-step drive matthew k senesky ∗, perry tsao†,sethrsanders ∗dept of electrical engineering and computer science, university of california, berkeley, ca 94720. Electric machines are used in the powertrains of electric and hybrid-electric ve- hicles to provide motoring or braking torque in response to the driver's request and power management logic. The electric machine is an electromechanical energy conversion device that processes and delivers power to the load the same electric machine can operate as a motor to convert electrical power to mechanical power or operate as a generator to convert mechanical power to electrical power. Electric drives - motor controllers and control systems (description and applications) purpose for many years the motor controller was a box which provided the motor speed control and enabled the motor to adapt to variations in the load. An electric drive is an electromechanical system that employs an electric motor as the prime mover instead of a diesel engine, steam or gas turbines, hydraulics, etc to control the motion and processes of different machines and mechanisms.
Performance evaluation of a cascaded h-bridge multi level inverter fed bldc motor drive in an electric vehicle a thesis by sriram sarma emani. The switched reluctance motor (srm) is a type of stepper motor, an electric motor that runs by reluctance torque unlike common dc motor types, power is delivered to windings in the stator (case) rather than the rotor. A device to store a large amount of electrical energy, b) an electrical machine to convert electrical power into mechanical torque on the wheels, c) a modified ice adapted to hybrid electric use, d) a transmission system between the two different propulsion techniques.
Abstract this doctoral thesis presents new ideas and research results on control of marine electric power system the main motivation for this work is the development of a control system, power. Induction machine is widely used in power system as an electric motor, but not the induction machine is widely used as electrical generators  although it has simplicity in construction. Composed of relatively simple electrical circuits and a control system with varying complexity in the scope of this thesis, a typical motor or generator can be modelled with high accuracy by two-dimensional fem, which is coupled with the circuit equations for the windings.
Electric vehicle control are good examples of these in aerospace, there are a number of applications, like centrifuges, pumps, robotic arm controls, gyroscope controls and so on. (1) as motor control systems age, the wear and tear on mechanical components may result in a loss of control, since the control system is tuned to the characteristics of the system when it was new. An electrical engineer works on different energies that include wind energy, solar energy, geo- thermal energy, fuel cell, turbine, hydro-energy, gas, etc being an engineering student, one has to get thesis topics for electrical engineering (eee) during their academics. The source of mechanical energy may shift generally from a hand wrench to an inward ignition motor a generator is a gadget that changes over mechanical energy to electrical energy for utilization in an outside circuit.
An abstract of a thesis dynamics and control of a battery inverter single-phase induction generator system obasohan i omozusi master of science in electrical engineering. Synchronous generator, permanent magnet machine, reluctance pm assisted motor, linear oscillatory motors, two rotors, single stator axial air-gap permanent magnet machine and complementary research directions such power electronics converters, are presented. Electric motors engineers who design electric machines need simulation tools that can be employed for quick, accurate product development by employing finite element methods early in the design process, they can accelerate development and achieve higher machine efficiencies using less material, which reduces costs.
