摘要：<p>The method involves controlling valves of an air loop by a dynamic pre-positioning set point in an efficient section coupled with a feedback loop, where valves are composed of a throttle (3), a metering air outlet (6), a low pressure exhaust gas recirculation loop (8), a high pressure exhaust gas recirculation loop (10) and an exhaust component (17). Gas flow traversing the valves is estimated from thermodynamic parameters of the air loop, where the thermodynamic parameters are estimated from pressure and temperature measurements carried out by a pressure sensor (5) equipped in the air loop.</p>
