1.5 hours
 
 Abstract:
Research Activities on power electronics and drives control at The University of Sheffield will be introduced for various applications from deep sea removed operated vehicles to aerospace applications.
Increasingly energy management is playing a crucial role in both stationary and vehicle applications with the rapidly increasing uptake of EV’s and grid connected energy storage. In some ways the requirements for energy management and battery health monitoring are identical in both applications, and in other ways, there are significant differences. This talk will discuss new and existing approaches to energy management and battery health monitoring in these applications, highlighting opportunities for innovation and simplification.
 
Speaker bio:
David Stone is professor of Electrical Engineering at the University of Sheffield, and leads the Center for Research into Electrical Energy Storage and Applications (CREESA) at Sheffield, including the facilities 2MW, 1MWhr Grid connected Energy storage research facility.
Prof Stone was appointed into the Electrical Machines and Drives (EMD) research group in 1989, and is heavily involved in EV / HEV research, together with energy conversion. He has led battery testing and management for over 15 years, being principal investigator on a number of industrially oriented projects together with more academic work on recycling and reuse of batteries on the grid, and Li-ion battery pack management. The battery work, coupled to power electronics, have resulted in over 250 papers in conferences and pier reviewed journals. Prof Stone manages the high power battery test facilities, capable of testing both single cells and battery strings within temperature controlled environments. The work done by Prof Stone and his colleagues forms the leading work on battery state of charge (SoC) and state of health (SoH) monitoring within the UK, and use of observers applied to batteries now allows the prediction of SoC and SoH for the batteries, increasing consumer confidence in battery powered vehicles.

Novel High Frequency Signal Injection Based Sensorless Control of PMSMs

Professor Z.Q. Zhu, FREng, FIEEE, FIET

University of Sheffield, UK

Summary

This presentation will firstly review various high frequency signal injection based sensorless control techniques for permanent magnet synchronous machines and then introduce a recently developed novel sensorlessmethod based on zero sequence voltage using either pulsating or rotating high frequency injection. The new method and features will be described in details and compared with those of conventional methods.
