REGULATION OF A SUPERCHARGING SYSTEM FOR INTERNAL COMBUSTION ENGINES

摘要

The supercharging system for an internal combustion engine comprises a plurality of exhaust-gas turbochargers which are connected in parallel to one another. One of the exhaust-gas turbochargers has an adjustable turbine guide geometry and is connected to an electric motor/generator. This results in two regulated systems, wherein the first regulated system regulates the motor/generator and the second regulated system regulates the adjustable guide geometry. A reference operating point of one exhaust-gas turbocharger is set by way of one of the two regulated systems, and the operating point of said exhaust-gas turbocharger is approximated or adapted to that of the other exhaust-gas turbochargers by way of the second regulated system.
