Air-path System Transient Control of Dual-Combustion- Mode Diesel Engine Based on Universal Sliding Mode Method

To address the Multiple Input Multiple Output (MIMO) control problem of air-path system in the combustion mode switching process of diesel engine, the transient control strategy of air-path system needs to be studied. A universal sliding mode controller suitable for all operating conditions was proposed to control the intake state during the transient combustion mode switching process. Therefore, the structure of the MIMO controller was greatly simplified. At the same time, a control-oriented numerical model was established to test the control system performance. It shows that the novel controller can effectively control the transient intake state, especially during the mode switching process.
