This book provides the current research on optimization methods for cooperative task allocation problems in drone fleets. Drone fleets, with their advantages of low cost, small size, and strong maneuverability, have been widely used in logistics, inspections, and other fields. However, it is a great challenge to cooperative task allocation when drone fleets are in large-scale tasks with task time constraints, temporal relationships, and performance requirements. To avoid the waste of resou...

This book discusses the challenges and solutions related to near-field millimeter-wave (MMW) imaging using MIMO arrays. Specifically, the authors focus on the issues of MMW imaging employing arrays in non-planar apertures, which have received limited attention in the existing literature, but are essential for security inspections using MMWs. This book introduces both the MIMO-SAR (using electronic and mechanical scanning) and fully electronic MIMO schemes. It develops and investigates vari...

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:

While the Chinese urban movement has successfully transferred surplus labor from the countryside to urban industries that urgently require free and cheap labor, numerous problems have arisen as a result of the unprecedented huge-scale process. Such conditions such as overcrowding, substandard housing, lack of social services, corruption, and abuse of power have often reached crisis stage. American college students often ask: How does the government control the largest urban population in t...

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...

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...
