Abstract: Integrated starter generator (ISG) uses one machine to replace
conventional starter and alternator onboard vehicles and provides greater
electrical generation capacity and improves the fuel economy and emissions.
The main requirements of the ISG control are to ensure:
- the necessary cranking torque as starter in the most unfavorable
conditions;
- a constant output voltage irrespective of the input speed (typically
between 600 and 8000 rpm) and load, as generator;
- a high efficiency as generator in the speed range of 600…4000 rpm that
corresponds both to I4 and V8 engines;
- an acceptable cost.
The idea
is not new, but needs a high complexity control system because of the
differences between motoring and generating regimes, so that only modern
motors and high-developed power electronics and digital signal processors
made it practically possible.
This presentation reviews the challenges and opportunities brought by the
integration of the internal combustion engine and ISG into a single power
unit. The structure evolution, material enhancement, and major design
challenges are discussed. The electric motors types that are suited to play
the role of an ISG are mostly the alternating current motors and their
control algorithms are analyzed and exemplified.
Brief
Biography of the Speaker:
Dorin-Dumitru Lucache received the M.S. and Ph.D. degrees from the "Gh.Asachi”
Technical University of Iasi, Romania, in 1986 and 2001, respectively, both
in electric engineering. He received also the M.S. in Mathematics and
Bussines Administration from the "A.I.Cuza” University of Iasi, Romania, in
1994 and 2007, respectively.
From 1986 to 1992, he worked as project engineer in the Land Works Execution
and Exploitation Industry, Iaşi, Romania and as research engineer in the
Building-Resistance National Research Institute, Iaşi, Romania. Beginning
1992 he becomes a member of the "Gh.Asachi” Technical University of Iasi,
Romania, currently acting as Assoc.Professor and Scientific Secretary of the
Faculty of Electrical Engineering.
He is a Member of IEEE, of AGIR (General Association of Engineers of
Romania) and of CETR (Technical Experts Council of Romania). He was chairman
of some sections in national and international conferences and organizing
committee chairman of three international conferences held in Iasi, Romania
and Chisinau, Rep. Moldavia.
Research fields of interest: permanent-magnet electric machines, magnetic
bearings, electric lighting and heating, mild-hybrid electric vehicles,
motion control.
Author/ co-author of more than 80 scientific papers, published in scientific
journals and/or presented at international/national conferences and 2 books
published in Romania. Coordinator/ member of the executive team of over 12
research and education grants, at national level.
