A model-based gain scheduling approach for controlling the common-rail system for GDI engines

Triple‐step method to design non‐linear controller for rail pressure of gasoline direct injection engines

“…With respect to control strategy, a model reference adaptive control algorithm based on the mean value model is proposed to reduce the residual pressure in the fuel rail [9]. In [10, 12], the control strategy is composed by a feedback integral action and a static model‐based feed‐forward action whose gains are scheduled as a function of fundamental plant parameters. In addition, in order to deal with the parameter variations because of uncertainties and disturbance, an active disturbance rejection control [13] and a discrete‐time integral minimal control [14] are recently presented.…”

A New Fuel-Injection Mechatronic Control Method for Direct-Injection Internal Combustion Engines

“…In this paper, we exercise a mathematical model describing the pressure dynamics in the common rail (CR) rail that is projected and experimentally validated in di Gaeta et al (2009Gaeta et al ( , 2011Gaeta et al ( , 2012). This mathematical model depicts the electrical dynamics of the EFI (fluidical valve), ignoring the effects owing to the movement of its plunger (i.e.…”

Switching Fractional-Order Controllers of Common Rail Pressure in Compressed Natural Gas Engines

“…The new idea is to combine the potentialities of robust FOPI controllers with a scheduling strategy, as it is usually made by combining standard integer order PI controllers with a scheduling policy [30], [4]. Scheduling the controller parameters takes into account the different CNG engine working conditions for fuel injection, i.e.…”

“…In this way, maps of controller gains are built for the different equilibrium points. This kind of strategy is common in many automotive applications [4], [23].…”
