Physical Modeling of a Turbocharger Electric Waste-Gate Actuator for Control Purpose 2017-24-0003

Gasoline engines have typically a waste gate actuator to control the boost pressure. The electrification of the vehicle and combustion engine components leads to new challenges of application of electric actuators in engine components, like turbochargers, which are faced with relatively high ambient temperatures. Another challenge is a simulation and prediction of the mechanical load on the actuator and kinematic components at different application scenarios, which can help to find the optimal solution which fulfills the durability, controllability, etc. targets. This paper deals with a physical dynamic model of an electric waste-gate actuator and kinematic components. The modeling includes a thermal, electrical and mechanical parts of the turbocharger control system and is validated on test-bench and engine measurements including pulsation effects. The measurements are accomplished on an modern turbocharged gasoline 4 cylinder engine EP gen2 Euro6.2 - China6 from PSA with the displacement volume of 1.6 liters.
