Abstract
Since engine controllers are generally implemented digitally, a model-based control approach points to the design of a discrete-time controller using a discrete-time plant model. However, the engine airpath is typically modeled in continuous time and must be discretized. The Euler method is a common discretization approach, but causes undesirable chattering in the turbocharged engine model. To mitigate this problem, a steady-state map of the throttle pressure ratio is used to eliminate a fast mode, resulting in a reduced-order model that is easily discretized.
