Book Description
Bachelor Thesis from the year 2012 in the subject Engineering - Power Engineering, grade: 10.0, Tribhuvan University (Institute of Engineering), course: Electrical Engineering, language: English, abstract: In this project, the performance of split-phase motor and three-phase induction motor drives for soft starting is evaluated. The pre systematically investigates and compares the characteristics of a variable voltage fed induction motor drive for two different types of soft starters; one based on IGBT and another based on Thyristor. The novelty of the work lies in the development of simple and flexible models for simulation purpose. This project investigates the influence of the parameters of the machine and of the soft starter on the dynamics of the induction machine start. The situations may reproduce actual situations occurred in practice, for example, the variation of initial voltage Vi, modification of the start time and load value. In this project we have investigated the relation between Total Harmonic Distortion and Power Factor of the IGBT and Thyristor based soft starter. Using an already predefined fire angle characteristic the influence of the initial voltage was also evaluated. Discussion of these results and conclusions as to the near-optimum types of profiles are delineated based on voltage and current profile fed to induction motor, starting times, and distortion in current with change in firing angle.

Book Description
This Special Issue deals with improvements in the energy efficiency of electric devices, machines, and drives, which are achieved through improvements in the design, modelling, control, and operation of the system. Properly sized and placed coils of a welding transformer can reduce the required iron core size and improve the efficiency of the welding system operation. New structures of the single-phase field excited flux switching machine improve its performance in terms of torque, while having higher back-EMF and unbalanced electromagnetic forces. A properly designed rotor notch reduces the torque ripple and cogging torque of interior permanent magnet motors for the drive platform of electric vehicles, resulting in lower vibrations and noise. In the field of modelling, the torque estimation of a Halbach array surface permanent magnet motor with a non-overlapping winding layout was improved by introducing an analytical two-dimensional subdomain model. A general method for determining the magnetically nonlinear two-axis dynamic models of rotary and linear synchronous reluctance machines and synchronous permanent magnet machines is introduced that considers the effects of slotting, mutual interaction between the slots and permanent magnets, saturation, cross saturation, and end effects. Advanced modern control solutions, such as neural network-based model reference adaptive control, fuzzy control, senseless control, torque/speed tracking control derived from the 3D non-holonomic integrator, including drift terms, maximum torque per ampere, and maximum efficiency characteristics, are applied to improve drive performance and overall system operation.

Book Description
This book provides the most important steps and concerns in the design of estimation and control algorithms for induction motors. A single notation and modern nonlinear control terminology is used to make the book accessible, although a more theoretical control viewpoint is also given. Focusing on the induction motor with, the concepts of stability and nonlinear control theory given in appendices, this book covers: speed sensorless control; design of adaptive observers and parameter estimators; a discussion of nonlinear adaptive controls containing parameter estimation algorithms; and comparative simulations of different control algorithms. The book sets out basic assumptions, structural properties, modelling, state feedback control and estimation algorithms, then moves to more complex output feedback control algorithms, based on stator current measurements, and modelling for speed sensorless control. The induction motor exhibits many typical and unavoidable nonlinear features.
