Boundary linear-quadratic control for a system of coupled parabolic-hyperbolic PDEs and ODE
Aksikas A.; Aksikas I.; Hayes R.E.; Forbes F. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)The paper deals with the design of a boundary optimal controller for a general model of parabolic-hyperbolic PDEs coupled with an ODE. The augmented infinite-dimensional state space representation has been used in order ... -
Characteristics-based model predictive control of selective catalytic reduction in diesel-powered vehicles
Pakravesh, H.; Aksikas, I.; Votsmeier, M.; Dubljevic, S.; Hayes, R. E.; Forbesa, F.... more authors ... less authors ( Elsevier Ltd , 2016 , Article)In heavy-duty diesel exhaust systems, selective catalytic reduction (SCR) is used to reduce NOx to nitrogen to meet environmental regulations. Diesel exhaust after-treatment involves a set of components that are best ... -
