“…GDI engine models have to cope with the complexity of the homogeneous and stratified combustion modes, and switching between them. Several control-oriented models have been described in the literature (see, for example, references [11] to [13]). Meanvalue engine models are generally accepted for engine control.…”

This paper presents an advanced model and control structure of a non-linear hybrid system: a gasoline direct injection (GDI) engine. The engine management system proposed in the paper is based on a hierarchical structure that uses Takagi-Sugeno fuzzy models of the engine to define piecewise linear controllers. Thanks to the hierarchical controller structure, engine idle speed regulation is tackled as a high-level requirement and therefore no specific low-level controller is needed. Moreover, the two combustion modes are correctly handled to optimize the engine efficiency. A global stability analysis of the GDI engine working either in homogeneous mode or in stratified mode is also presented, based on bifurcation analysis. Bifurcation analysis can be applied to a wide range of different controllers (even close-toproduction), and therefore it can be of significant practical value.
