This paper introduces a model-based controller designed to minimize the total unburned hydrocarbons produced by the internal combustion engine and processed by the three way catalytic converter, during the warm-up period.
We assume to feed back the temperature of the exhaust gas; having in mind to decouple the control of combustion from the control of intake manifold, we assumed as controllable inputs the flow of air and fuel into the cylinder and the spark advance. The outputs are the total unburned hydrocarbons pre and post converter.
