Towards a Stronger Simulation Support for Engine Control Design: a Methodological Point of View

Towards a Stronger Simulation Support for Engine Control Design: a Methodological Point of View — Thanks to a specific crank angle degree modelling approach and to an accurate simulator calibration, it is nowadays possible to build a complete simulator which allows the control engineer to access to numerous engine variables, especially non measurable values, and to perform tests over a wide range of operating conditions. Hosted in a dedicated platform, the engine simulator can support the control system design at each stage of the development cycle. Its use starts with the local dynamics understanding of the engine behaviour and ends with the real time control pre-calibration.
