The book presents a focused study on electrolytic capacitorless permanent magnet synchronous motor (PMSM) drives and their associated control strategies. It addresses both theoretical foundations and engineering practices through a comprehensive exploration of key topics, including system modeling, analytical principles for engineering challenges, control method design, experimental validation, and performance evaluation.Five critical engineering challenges are examined in depth:

This book focuses on the advanced control of reduced dc-link capacitance AC motor drives. Compared with the conventional AC motor drives, the reduced DC-link capacitance motor drives could reduce the cost, enhance the reliability and improve the power density. The control strategies proposed in this book are verified by experimental results, which include high power factor control, drive system stability control, beat phenomenon suppression, enhanced flux-weakening control, anti-overvoltag...

The book focuses on position sensorless control for PMSM drives, addressing both basic principles and experimental evaluation. It provides an in-depth study on a number of major topics, such as model-based sensorless control, saliency-based sensorless control, position estimation error ripple elimination and acoustic noise reduction. Offering a comprehensive and systematic overview of position sensorless control and practical issues it is particularly suitable for readers interested in the...

This book focuses on the control strategies for gearless permanent magnet synchronous motor traction elevators. Both basic principles and experimental evaluation have been addressed. This is achieved by providing in-depth study on a number of major topics such as speed detection at low-speed operation, starting torque strategy based on dichotomy and staircase methods, fuzzy self-tuning method, MPC and ADRC, etc. The comprehensive and systematic treatment of control strategies for cost-effe...

Algae are sunlight-driven cell factories, and can efficiently absorb CO2 and convert light energy to chemical energy such as lipid, starch and other carbohydrates and release O2. Algal feedstock is a promising resource for bioproduct production, given its high photosynthetic efficiency for producing biomass compared to conventional crops. Microalgae can be used for flue-gas and wastewater bioremediation. This book highlights recent breakthroughs in the multidisciplinary areas of algal biot...

This book is on mobile networks with the emphasis on mobile data services.Mobile Network Operators (MNOs) monetize the scarce wireless spectrum resource, generating revenue through the provision of mobile data services to their customers. The traditional mobile data service is a three-part tariff involving a monthly data quota. This kind of service lacks for flexibility seriously, since it rigidly dictates the usage of data based on time, location, and user identity, limiting when,...

China in the Era of Social Media discusses how social media is changing the world in an unprecedented way through speed, scope, and depth. In the last decade or so, social media in China has witnessed the most explosive growth in the world. Being the most populous nation in the world, it has the most social media users in the world as well. This book examines the current situation and unique characteristics of Chinese social media, the significance of social media in the country’s...

"Five-Year Plans" have been a cornerstone of Chinese social and economic development initiatives since 1953. During the thirteenth of these periods between 2016 and 2020, the global economy has experienced instability after the financial crisis, as well as political and economic reconfiguration. Drawing on modern economic theory, this book comprehensively discusses China's economic development in this crucial phase.The book analyzes the international economic environment, and asks ...
