One of the earliest international authorities on electric vehicles, C.C. Chan has been at the forefront of developing technologies enabling clean and efficient transportation methods benefiting the environment. Chan has made extraordinary contributions to the theoretical analysis and optimization of electric machines, power electronic devices, converters, special mechanical structures, and cooling systems that meet the special needs of electric vehicles including adaptive decoupling control, electromagnetic and thermal field analysis, hybrid architectures, and energy management. Considered the first comprehensive book on the topic, Chan’s Modern Electric Vehicle Technology provided the fundamentals for modern electric vehicle technology, addressed key issues, and assessed their environmental impact. His recent research in smart charging and vehicle-to-grid systems has gained attention from not only automakers but also power utilities.
An IEEE Fellow, Chan is a professor with the University of Hong Kong’s Department of Electrical and Electronic Engineering, Hong Kong.
Claire J. Tomlin’s control systems expertise is making air transportation systems safer through collision avoidance techniques and avionics safety verification methods. Tomlin’s algorithms allow the development and analysis of control protocols that have guarantees of safety for hybrid system models, which represent the kinds of switched dynamical systems found in air transportation systems. Her work has been tested in simulation, on unmanned aerial vehicle test flights, and flown on commercial platforms. She built one of the first quadrotor testbeds for experimentation with these control protocols. Her methods were used to compute collision zones for two aircraft paired approaches and were flown on a Boeing T-33 test aircraft that was able to avoid collision with an F-15 flying “blunders” into its path. Her work is also integral to the development of the Next Generation Air Transportation System for modernizing air traffic control.
An IEEE Fellow, Tomlin is the Charles A. Desoer Chair in Engineering (EECS) at the University of California, Berkeley, CA, USA.
The pioneering innovations of Petros Ioannou have been instrumental in making adaptive cruise control (ACC) a practical reality and spurring its commercial adoption by the automotive industry. Using forward-looking sensors such as radar, ACC systems automatically adjust a vehicle’s speed to maintain a safe driving distance based on vehicles ahead of it. Unique to Ioannou’s work was implementing a time-headway approach to vehicle spacing instead of the popular belief of using vehicle-to-vehicle communications. By avoiding the complications of vehicle-to-vehicle communications, manufacturers such as Ford were able to bring ACC technology to market quickly. Ioannou’s ACC systems also provide smoother acceleration and speed response, which have demonstrated positive effects on traffic flow, fuel economy, and the environment.
An IEEE Fellow, Ioannou is a professor with the University of Southern California, Director of the Center for Advanced Transportation Technologies, and Associate Director of Research of the University Transportation Center METRANs, Los Angeles, CA, USA.
Robert D. King has devoted his 35-year career to changing the world’s dependence on fossil-fuel-driven vehicles. Known as GE’s “father of electric vehicle research and development,” over 50% of today’s hybrid-electric vehicles incorporate patents developed by Mr. King and his research team. He has been responsible for the design, development, and testing of electric and hybrid vehicle propulsion systems for the GE Hybrid Locomotive program, GE Hybrid Package Delivery Truck, GE/FTA Low Emissions Hybrid Bus Program, Modular Electric Vehicle Program, and the GE/DOE Hybrid Test Vehicle. Using compact ac traction drives and novel energy management system controls, Mr. King has demonstrated substantially reduced petroleum consumption for on-road hybrid passenger cars and reduced transit bus emissions via hybridization.
An IEEE Life Fellow, Mr. King, a senior electrical engineer with GE Global Research, Schenectady, NY, USA, retired in 2014.
A driving force in automotive electrical systems, Linos J. Jacovides’ visionary development of electric drives and systems has set the foundation for the technologies that power today’s electric and hybrid vehicles. Among Dr. Jacovides’ essential innovations that span over 40 years was the development a 4,000-horsepower induction motor drive for locomotives. He and his team also introduced automotive electronic systems, including exhaust oxygen sensors, micromechanical accelerometers, fuel injectors, electric power steering, and permanent magnet motors for propulsion and accessories. The design tools he developed during the 1970s are still in use for producing drives for today’s electric/hybrid vehicles. Since retiring as director of Delphi Research Labs in 2007, Dr. Jacovides has participated in several National Academies studies on fuel efficiency and hybrid vehicles.
An IEEE Fellow, Dr. Jacovides lives in Grosse Pointe, MI, USA.
