Development of Coordinated Algorithm of EGR and Boost Pressure based on the Adaptive Sliding Mode Control 2008-01-0996

In case of the turbocharged engine, it is difficult to control both the air mass flow and the EGR flow. Because the air mass flow and the Exhaust Gas Recirculation (EGR) flow are influenced by the boost pressure, it becomes necessary to manipulate the many inputs to control them.
Therefore, to overcome this problem, we developed the new Multi Input Multi Output (MIMO) algorithm based on the adaptive sliding mode control (SMC) which eliminated the observer. And consequently, it is confirmed that this new algorithm makes it possible to track both the air mass flow and EGR flow to the desired value.
