“…Categorized by the controller structure, two types of schemes are applied in closed-loop fuel injection control. First, a decoupled scheme containing multiple single-input singleoutput (SISO) controllers, which leads to diagonally structured K p and K i , i.e., [4], [9]- [11]. Second, a coupled scheme containing a multi-input multi-output (MIMO) controller, such that K p and K i contain non-zero off-diagonal entries, see [12].…”

“…This is due to the fact that, in this case, there are multiple combustion events in one cycle, where the latter combustion events are influenced by the previous ones. A decoupled fuel injection control scheme results in unsatisfactory dynamic performance with coupled tracking behavior [9], long settling time [11] and overshoot [12]. Therefore, it is desired to apply a multivariable (coupled) control scheme in advanced diesel combustion with multi-pulse fuel injection.…”

“…With the inclusion of technologies like EGR, variable geometry turbochargers (VGT), diesel engines are becoming increasingly complicated. As such, simple rule-based control strategies or methods based on look-up tables [5,6] are not always satisfactory on these more complex engines and the automotive industry has turned to model-based and closed loop control techniques on modern engines [7,8]. These model-based control strategies have been used to accurately control engine processes including air flows, in-cylinder gas composition and combustion timing.…”

Because fuel efficiency is significantly impacted by the timing of combustion in internal combustion engines, accurate control of combustion phasing is critical. In this paper, a nonlinear combustion phasing model is introduced and calibrated, and both a feedforward model-based control strategy and an adaptive model-based control strategy are investigated for combustion phasing control. The combustion phasing model combines a knock integral model, burn duration model and a Wiebe function to predict the combustion phasing of a diesel engine. This model is simplified to be more suitable for combustion phasing control and is calibrated and validated using simulations and experimental data that include conditions with high exhaust gas recirculation fractions and high boost levels. Based on this model, an adaptive nonlinear model-based controller is designed for closed-loop control, and a feedforward model-based controller is designed for open-loop control. These two control approaches were tested in simulations. The simulation results show that during transient changes the CA50 (the crank angle at which 50% of the mass of fuel has burned) can reach steady state in no more than 5 cycles and the steady state errors are less than ±0.1 crank angle degree (CAD) for adaptive control, and less than ±0.5 CAD for feedforward model-based control.
