Optimization-based non-linear Control Law with Increased Robustness for Air Fuel Ratio Control in SI Engines
In spark ignition (SI) engines, the accurate control of air fuel ratio (AFR) in the stoichiometric value is required to reduce emission and fuel consumption. The wide operating range, the inherent nonlinearities and the modeling uncertainties of the engine system are the main difficulties arising in the design of AFR controller. In this paper, an optimization-based nonlinear control law is a...
متن کاملModel predictive control for automotive time-delay processes: An application to air-to-fuel ratio control ⋆
To meet increasingly stringent emission regulations modern internal combustion engines require highly accurate control of the air-to-fuel ratio. The performance of the conventional air-to-fuel ratio feedback loop is limited by the combustion delay between fuel injection and engine exhaust, and by the transport delay for the exhaust gas to propagate to the air-to-fuel ratio sensor location. The ...
متن کاملSpark Ignition Engine Fuel-to-Air Ratio Control: An Adaptive Control Approach
This paper presents the control of Spark Ignition (SI) Internal Combustion (IC) engine Fuel-to-Air Ratio (FAR) using an adaptive control method of time-delay systems. The objective is to maintain the in-cylinder FAR at a prescribed set point, determined primarily by the state of the Three-Way Catalyst (TWC), so that the pollutants in the exhaust are removed with the highest efficiency. The FAR ...
متن کاملA neural-network based control solution to air-fuel ratio control for automotive fuel-injection systems
Maximization of the catalyst efficiency in automotive fuel-injection engines requires the design of accurate control systems to keep the air-to-fuel ratio at the optimal stoichiometric value AF . Unfortunately, this task is complex since the air-to-fuel ratio is very sensitive to small perturbations of the engine parameters. Some mechanisms ruling the engine and the combustion process are in fa...
متن کاملModel-Based Adaptive Air/Fuel Ratio Control for an Automotive Gasoline Engine
This thesis presents the design of an adaptive air/fuel ratio control system incorporating a λ sensor with varying dynamical properties. As a baseline, the design of a nominal non-adaptive air/fuel ratio controller based on the internal model control principle is presented. For the adaptation of the λ sensor dynamics two different adaptive methods tailormade for the internal model control struc...
