Abstract
This paper develops nonlinear models for diesel±electric powertrains used in medium- and heavy-duty
hybrid-electric vehicles and describes a new method for designing optimal controllers for highly coupled
drivetrains. Current applications of heavily loaded, heavy-duty drives call for the use prehensive,
innovative ways of handling a large variety of nonlinear phenomena in order to optimize performance
and energy conversion, to shape steady-state characteristics and to meet other desired speci®cations. It is
evident that energy conversion and optimal energy management should be integrated and thoroughly
studied. This paper demonstrates the application of derived nonlinear models of ponents
(diesel, synchronous generator, traction motor) analyzes the nonlinear energy conversion and develops
an innovative design method to control these highly nonlinear diesel±electric systems. Fundamental
analysis and design methods, such as the Lyapunov stability theory and admissibility concept, are used
to attain nonlinear analysis, design and motion control. The developed concept in nonlinear analysis
and design allows one to synthesize optimal tracking controllers for highly nonlinear systems with
minimal approximating simpli®cations and assumptions used in the model development. New promising
analytical results are presented along with a supporting example involving a controlled, 40-ton vehicle
with a hybrid-electric drivetrain. Experimental data is reported to validate the results. # 1999 Elsevier
