| Summary: | "better" non-overshooting response while at the same time a feedback controller to be designed to close the loop so achieving other feedback objectives is feasible. and fast air-fuel ratio (AFR) control in combustion engines. and fuel mass input into the combustion cylinder each cycle and predicts only one value of AFR in the cylinder for each averaging engine model was derived in the time-domain, using be superior to that with the H2optimal controller. be used to design a "better" AFR control system. First, an combustion (IC) engine and proposes an engine model which can continuous differential equations. H2-optimal control cycle. From a controls viewpoint, this is more useful. The cylinder pressure information is presented. Analysis, derived. The model was linearized and discretized to an engine model and a classical feedback-feedforward controller event-based model which requires only one value of air mass for synthesizing a control system for an automotive internal Increasingly strict emission standards require very accurate located in the exhaust manifold. The analysis, results and model was analyzed and proven to have enough information for objectives. A proposed control scheme based on the in- overshooting response. This design was based on the current performance with the pressure-based controller is believed to Second, a non-averaging, cyclic, crank angle domain model was shortcomings of this design methodology are presented. simulations and results are presented. The achievable state-of-the-art exhaust gas oxygen (EGO) sensor which is that the response of the system meets the specified theories for robust design were applied to the linearized Therefore, with the pressure information, design for a This thesis addresses the design methodology currently used was designed, which strives to achieve robust non- |
