“…In reference [25], robustness to disturbances, plant uncertainty and measurement noise were addressed with careful attention to the sensitivity and complementary sensitivity functions in the frequency range of interest. Reference feedforward control has also been proposed [26], which is applied to the ISC system of GDI engines during lean burn. GDI engine ISC has also been analysed with the hybrid systems formalism.…”

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.
