Sajidul Qadir and published by Lulu.com. This book was released on 2013-07-13 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Mathematical Modelling of a reference SEDM has been done & Transfer Function has been derived with simulated result. Later Parameter Identification has been carried out to find the suitable design criteria for testing different controllers (P, PI, PD, PID controllers) with the machine. As it turned out to be a stable system (as per Routh-Hurwitz Stability Criterion), different controllers has been used to evaluate the Step response of Open loop & Closed loop system with simulated result. Controller tuning has been done to find the best result for controlling speed of SEDM. Settling time, % Overshoot, Steady-State error & Rise time has been calculated for all the controllers. Later active RC realization of the best fitted controller has been done using Ideal PID Control Algorithm.

Download or read book Neural Fuzzy Control Systems With Structure And Parameter Learning written by Chin-teng Lin and published by World Scientific Publishing Company. This book was released on 1994-02-08 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general neural-network-based connectionist model, called Fuzzy Neural Network (FNN), is proposed in this book for the realization of a fuzzy logic control and decision system. The FNN is a feedforward multi-layered network which integrates the basic elements and functions of a traditional fuzzy logic controller into a connectionist structure which has distributed learning abilities.In order to set up this proposed FNN, the author recommends two complementary structure/parameter learning algorithms: a two-phase hybrid learning algorithm and an on-line supervised structure/parameter learning algorithm.Both of these learning algorithms require exact supervised training data for learning. In some real-time applications, exact training data may be expensive or even impossible to get. To solve this reinforcement learning problem for real-world applications, a Reinforcement Fuzzy Neural Network (RFNN) is further proposed. Computer simulation examples are presented to illustrate the performance and applicability of the proposed FNN, RFNN and their associated learning algorithms for various applications.

"The third edition includes additional diagrams and worked examples throughout. Now topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded."--BOOK JACKET.

Download or read book Bangladesh s Economic and Social Progress written by Munim Kumar Barai and published by Springer Nature. This book was released on 2020-03-31 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates Bangladesh’s impressive economic and social progress, more often referred to as a ‘development surprise’. In doing so, the book examines the gap in existing explanations of Bangladesh’s development and then offers an empirically informed analysis of a range of distinctive factors, policies, and actions that have individually and collectively contributed to the progress of Bangladesh. In an inclusive way, the book covers the developmental role, relation, and impact of poverty reduction, access to finance, progress in education and social empowerment, reduction in the climatic vulnerability, and evolving sectoral growth activities in the agriculture, garments, and light industries. It also takes into account the important role of the government and NGOs in the development process, identifies bottlenecks and challenges to Bangladesh’s future development path and suggests measures to overcome them. By providing an inclusive narrative to theorize Bangladesh’s development, which is still missing in the public discourse, this book posits that Bangladesh per se can offer a development model to other developing countries.

Download or read book Energy Security written by Adrian V. Gheorghe and published by Springer. This book was released on 2011-02-09 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: In terms of energy security the Black Sea region is important to Europe. Inevitably and for very good reasons, a lot of attention has been given to the existing and planned pipeline routes going around or across the Black Sea. Much less attention has been given to the development of the Black Sea energy market in its own right and to the potential advantages of coping with some current and future energy issues in a multilateral regional format rather than through individual action at national level. The present book addresses, in a comprehensive manner, the current problematic of energy security and goes beyond pipeline politics, without playing down their continued significance; it addresses some topical questions related to the sustainability and resilience of energy systems as applicable to the Black Sea region.

Book excerpt: Machine tools are the main production factor for many industrial applications in many important sectors. Recent developments in new motion devices and numerical control have lead to considerable technological improvements in machine tools. The use of five-axis machining centers has also spread, resulting in reductions in set-up and lead times. As a consequence, feed rates, cutting speed and chip section increased, whilst accuracy and precision have improved as well. Additionally, new cutting tools have been developed, combining tough substrates, optimal geometries and wear resistant coatings. “Machine Tools for High Performance Machining” describes in depth several aspects of machine structures, machine elements and control, and application. The basics, models and functions of each aspect are explained by experts from both academia and industry. Postgraduates, researchers and end users will all find this book an essential reference.

Download or read book Swarm Stability and Optimization written by Veysel Gazi and published by Springer Science & Business Media. This book was released on 2011-02-01 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swarming species such as flocks of birds or schools of fish exhibit fascinating collective behaviors during migration and predator avoidance. Similarly, engineered multi-agent dynamic systems such as groups of autonomous ground, underwater, or air vehicles (“vehicle swarms”) exhibit sophisticated collective behaviors while maneuvering. In this book we show how to model and control a wide range of such multi-agent dynamic systems and analyze their collective behavior using both stability theoretic and simulation-based approaches. In particular, we investigate problems such as group aggregation, social foraging, formation control, swarm tracking, distributed agreement, and engineering optimization inspired by swarm behavior.
