High automotive hydrocarbon emission during cold start is a well recognized challenge with increasing importance in moving towards green vehicles. In this work the application of a linear model reduction technique on the design of a controller for a nonlinear system is discussed. A reduced order cold start model of an SI engine and aftertreatment system is realized using a balanced truncation technique. Sliding mode controllers, derived from a nonlinear physical model and the reduced order model, are designed to reduce tailpipe hydrocarbon emissions. The comparison results indicate the controller derived from the balanced truncated model performs better since it adjusts the control inputs such that it favors the certain desired trajectories which are more influential on the final control target.
