Modeling and control of gasoline direct injection stratified charge (DISC) engines

In this paper, we present a phenomenological nonlinear dynamic model for direct injection stratified charge (DISC) gasoline engines and discuss several key control problems for this advanced technology powertrain. The model is developed and validated using dynamometer engine mapping data obtained from a 4-cylinder DISC engine. It captures the static behavior of the key components of a DISC engine, such as the torque and emissions generation and volumetric efficiency, as well as the essential dynamics for the intake manifold and engine rotational inertia. It is shown that the multimode operation of a DISC engine dictates a hybrid model structure and also requires a coordinated multivariable control strategy to achieve expected performance.

Editorial: Special Issue on Control Applications in Automotive Engineering

The 18 papers in this special issue focus on control applications in automotive engineering. The papers cover issues ranging from controlling engines and alternative powerplants (such as fuel cells), to issues in transmission, driveline, and integrated powertrain control (including hybrid electric vehicle control), and finally, to vehicular chassis control applications.
