Automotive engine hybrid modelling and control for reduction of hydrocarbon emissions

摘要: Automotive engine models vary in their complexity depending on the intended application. Pre-prototype performance prediction can be very complex order to make accurate predictions. Controller design need as simple possible since model-based controllers must operate real time. This paper develops hybrid for control that incorporate time and events formulation. The resulting have capability of switching between two alternative modes. first mode is designed reduce raw hydrocarbon (HC) emissions while second tries increase temperature catalytic converter rapidly during initial transient or “cold start” period. Reachability, a tool system analysis, used verify properties closed loop system.
