In order to understand the selection of electric machines and sensors utilized in Hybrid Electric vehicles, background material is presented.  Fundamentals of linear motion electro-mechanical devices such as relays and solenoids are presented, followed by rotating machines.  DC and AC machines will be discussed along with the practical aspects of commutation and induction.

For proper control, the appropriate sensors are required.  A selection of common sensors will be presented with emphasis on applications, advantages and limitations.

With the background established, the selection of variable frequency synchronous motors with resolver sensors is discussed.  Non-automotive and automotive applications will be discussed.

Biography: Dr. Hideg is a Technical Specialist with Chrysler Corporation in the Hybrid Electric Vehicle (HEV) Department.  His current assignment is Electric Motor Control Development including propulsion, engine start/stop and regenerative braking functions.  His prior assignment was hydraulic controls for the six speed Chrysler transmission as well as for the HEV (then DaimlerChrysler).  He also developed control strategies of electric oil pumps for the Chrysler and Mercedes HEVs.

Before joining Chrysler, Dr. Hideg was an Associate Professor of Electrical Engineering at Lawrence Technological University.  He taught undergraduate and graduate courses in electronics, control systems and electrical machines.  During his tenure, he consulted at Otis Elevators, Ford Research and Ford Electrical and Fuel Handling Division (now Visteon).  He also consulted with Chrysler Manufacturing evaluating new technologies.

He has published over 30 papers on control systems and has offered internal courses at Chrysler on Signals and Filters as well as Hydraulics Controls.  Dr. Hideg has also served on several IEEE conference committees.  He received his PhD from Oakland University, Rochester, Michigan and holds a BS and MS from the University of Michigan.
