This paper considers optimal control of glycerol producing 1, 3-propanediol (1, 3-PD) via
microbial fed-batch fermentation. The fed-batch process is formulated as a nonlinear …

In practical optimal control problems multiple and conflicting objectives are often present,
giving rise to a set of Pareto optimal solutions. Although combining the different objectives …

The three way catalytic converter (TWC) is a critical component for the mitigation of tailpipe
emissions of modern spark ignition internal combustion (IC) engines. Because the TWC …

An adaptive, state-space, model-predictive controller for spark ignition (SI) engine air–fuel
ratio control is developed and presented in this brief. The linear model-based controller is an …

The paper presents a novel control-oriented, first-principle model of a three-way catalytic
converter (TWC). The model accurately predicts the air–fuel ratio downstream of the catalyst …

In this work, a discrete, time-based, delay-compensated, adaptive PID control algorithm for
air fuel ratio control in an SI engine is presented. The controller operates using feedback …

A novel linear state-space model predictive controller for SI engine air fuel ratio control is
presented and demonstrated over a range of engine operation. The linear model-based …

Numerous models for the simulation of chemical phenomena in three-way catalytic
converters (3WCCs) have been proposed in the literature, ranging from models of the …

In this work, a model predictive functional control approach for automotive three-way catalyst
oxygen storage state control is demonstrated on a Ford 2.0 liter I4 Duratec SI engine. The …

Reducing exhaust emissions is one of the biggest challenges facing the automotive
engineering community today. In order to comply with future more stringent emission …
