The complexity of AC motor control lies in the multivariable andnonlinear nature of AC machine dynamics. Recent advancements incontrol theory now make it possible to deal with long-standingproblems in AC motors control. This text expertly draws on thesedevelopments to apply a wide range of model-based controldesignmethods to a variety of AC motors. Contributions from over thirty top researchers explain howmodern control design methods can be used to achieve tight speedregulation, optimal energetic efficiency, and operation reliabilityand safety, by considering online state variable estimation in theabsence of mechanical sensors, power factor correction, machineflux optimization, fault detection and isolation, and faulttolerant control. Describing the complete control approach, both controller andobserver designs are demonstrated using advanced nonlinear methods,stability and performance are analysed using powerful techniques,including implementation considerations using digital computingmeans. Other key features: • Covers the main types of AC motors including triphase,multiphase, and doubly fed induction motors, wound rotor, permanentmagnet, and interior PM synchronous motors • Illustrates the usefulness of the advanced controlmethods via industrial applications including electric vehicles,high speed trains, steel mills, and more • Includes special focus on sensorless nonlinearobservers, adaptive and robust nonlinear controllers,output-feedback controllers, fault detection and isolationalgorithms, and fault tolerant controllers This comprehensive volume provides researchers and designers andR&D engineers with a single-source reference on AC motorsystem drives in the automotive and transportation industry. Itwill also appeal to advanced students in automatic control,electrical, power systems, mechanical engineering and robotics, aswell as mechatronic, process, and applied control systemengineers.

This monograph shows the reader how to avoid the burdens of sensor cost, reduced internal physical space, and system complexity in the control of AC motors. Many applications fields—electric vehicles, wind- and wave-energy converters and robotics, among them—will benefit. Sensorless AC Electric Motor Control describes the elimination of physical sensors and their replacement with observers, i.e., software sensors. Robustness is introduced to overcome problems associated with the unavoidable imperfection of knowledge of machine parameters—resistance, inertia, and so on—encountered in real systems. The details of a large number of speed- and/or position-sensorless ideas for different types of permanent-magnet synchronous motors and induction motors are presented along with several novel observer designs for electrical machines. Control strategies are developed using high-order, sliding-mode and quasi-continuous-sliding-mode techniques and two types of observer–controller schemes based on backstepping and sliding-mode techniques are described. Experimental results validate the performance of these observer and controller configurations with test trajectories of significance in difficult sensorless-AC-machine problems. Control engineers working with AC motors in a variety of industrial environments will find the space-and-cost-saving ideas detailed in Sensorless AC Electric Motor Control of much interest. Academic researchers and graduate students from electrical, mechanical and control-engineering backgrounds will be able to see how advanced theoretical control can be applied in meaningful real systems.

The book provides readers with a snapshot of recent research and technological trends in the field of condition monitoring of machinery working under a broad range of operating conditions. Each chapter, accepted after a rigorous peer-review process, reports on an original piece of work presented and discussed at the 4th International Conference on Condition Monitoring of Machinery in Non-stationary Operations, CMMNO 2014, held on December 15-16, 2014, in Lyon, France. The contributions have been grouped into three different sections according to the main subfield (signal processing, data mining or condition monitoring techniques) they are related to. The book includes both theoretical developments as well as a number of industrial case studies, in different areas including, but not limited to: noise and vibration; vibro-acoustic diagnosis; signal processing techniques; diagnostic data analysis; instantaneous speed identification; monitoring and diagnostic systems; and dynamic and fault modeling. This book not only provides a valuable resource for both academics and professionals in the field of condition monitoring, it also aims at facilitating communication and collaboration between the two groups.
