Modeling and Control of Electronic Throttle Drive

The automotive drive-by-wire or electronic throttle system has facilitated notable improvements in fuel economy of internal combustion engines and enhanced performance of other vehicle systems such as automatic transmissions and traction control systems. The book presents a comprehensive and experimentally verified approach to modeling, identification, and position control of the electronic throttle DC drive. Since the electronic throttle is characterized by notable nonlinear effects due to gearbox friction and a dual return spring, and is also subject to production deviations and parameter variations, special attention is given to compensation of friction and return spring nonlinearities, and on-line adaptation of the control system. The overall nonlinear control strategy is embedded and experimentally examined within a spark-ignition engine idle speed control system. The book may be useful for researchers and practitioners within the fields of automotive systems and industrial servodrives, as well as to engineering educators dealing with electrical servodrives, automotive mechatronics, and control system applications.
