“…As a consequence, the piston is pushed down with the shutter, letting more fuel to enter in the main chamber, where the pressure increases. On the contrary, when the solenoid valve is non-energized, the pressure on the upper side of the piston decreases, making the piston to raise and the main chamber shutter to close under the action of a preloaded spring (see (Lino et al, 2006) for details).…”

“…They predict the output from a process model and then impress a control action able to drive the system to a reference trajectory (Rossiter, 2003). A 2 nd order state space analytical model of the plant (Lino et al, 2006) is used to derive a predictive control law for the injection pressure regulation. The model trades off between accuracy in representing the dynamical behaviour of the most significant variables and the need of reducing the computational effort and complexity of controller structure and development.…”

“…By considering the duty cycle of the signal driving the solenoid valve and the rail pressure as the input u and output y respectively, a family of ARX models can be obtained, according the above mentioned design steps (Lino et al, 2006):…”

“…At each step, the first computed control action is applied and then the optimization process is repeated after updating all vectors. It can be shown (Lino et al, 2006) that the resulting control law for the case study becomes:…”

This paper describes the integrated design of the pressure control in a common-rail injection system. Mechanical elements and the embedded controller are considered as a whole, using a multidisciplinary approach to modelling and simulation. The virtual prototype, which provides the detailed geometrical/physical model of the mechanical parts, plays the role of a surrogate of a reference hardware prototype in reduced-order modelling, validation, and/or in tuning the control parameters. The results obtained by the proposed approach are compared and validated by experiments.

“…Also, due to the existing integration between input variable v c and one of the state variables, direct use of MPC would be problematic. To make use of MPC properties and resolve its deficiencies, a two-layer architecture [11][12][13] with cascade configuration is proposed here. In the inner loop of the architecture, the previously designed PI controllers are applied and in the outer loop a constraint GPC is implemented.…”
