Despite that, literature on control design for those systems is scarce, and there is a real need for investigating approaches that can be effective in an industrial context, where rapid control prototyping must be followed by a viable calibration procedure. The paper describes modeling and control of a pilot Rankine steam process for exhaust gas heat recovery from a spark-ignition engine, focusing in particular on the use of a reduced-order dynamic model of the system to compute a nonlinear feedforward action to better control the system during nominal operation. Model reduction is obtained at the heat-exchanger level. First, via the moving-boundary approach, which avoids the need for complex, finite-volume, models. Then, via a further reduction of the resulting evaporator model which captures its dominant dynamics. The proposed control system is validated on a detailed reference simulator using a demanding driving cycle. %G English %2 https://ifp.hal.science/hal-00875423/document %2 https://ifp.hal.science/hal-00875423/file/Peralez-et-al_VPPC2012.pdf %L hal-00875423 %U https://ifp.hal.science/hal-00875423 %~ IFP %~ CNRS %~ UNIV-LYON1 %~ LAGEP %~ DUFOUR-PASCAL-C-3926-2008 %~ DYCOP %~ UDL %~ UNIV-LYON %~ LAGEPP
