Abstract
A control apparatus for an internal combustion engine has an exhaust-gas turbocharger regulator which, as a function of a setpoint boost pressure and an actual boost pressure, determines a controlled actuating-variable exhaust-gas back-pressure. An exhaust-gas recirculation regulator determines, as a function of a setpoint air mass flow and an actual air mass flow, a controlled actuating-variable exhaust-gas recirculation mass flow. A first decoupling unit determines a decoupling mass flow in an exhaust-gas section. A second decoupling unit determines a decoupling exhaust-gas back-pressure. A first conversion unit determines a signal for the exhaust-gas turbocharger actuator as a function of the pilot-control actuating-variable exhaust-gas back-pressure, the controlled actuating-variable exhaust-gas back-pressure and the decoupling mass flow. A second conversion unit determines a signal for the exhaust-gas recirculation valve as a function of the pilot-control actuating-variable exhaust-gas recirculation mass flow, the controlled actuating-variable exhaust-gas recirculation mass flow and the decoupling exhaust-gas back-pressure.
