Dynamic simulation and optimisation of tubular polymerisation reactors in gPROMS
(Pergamon-Elsevier Science Ltd, 2001-05-12)
In this paper a dynamic model of the high-pressure polymerisation of ethylene in tubular reactors is introduced and a dynamic optimisation problem is formulated for studying start-up strategies. The optimisation objectives ...
Structural shape optimisation using boundary elements and the biological growth method
(Springer, 2004-09)
A numerical evolutionary procedure for the structural optimisation for stress reduction of two-dimensional structures is presented in this paper. The proposed procedure couples the biological growth method (BGM) with the ...
Environmental life cycle assessment as a tool for process optimisation in the utility sector
(Elsevier, 2005-05)
A methodology is presented to calculate the optimum operating conditions of a petrochemical plant utility sector, to minimize the overall Life Cycle Environmental Impact. The battery limits of the system studied are extended ...

Game approach to distributed model predictive control
(Inst Engineering Technology-iet, 2011-10)
This study introduces a framework for distributed model predictive control (MPC) based on dynamic games, where centralised and decentralised control algorithms can be viewed as dynamical games with coupled control sets. ...
Dynamic Modelling and Optimisation of Large-Scale Cryogenic Separation Processes
(Italian Association of Chemical Engineering, 2005-06)
In this work, the open loop dynamic optimisation of a large-scale natural gas processing plant is performed. A rigorous differential-algebraic equation (DAE) model has been formulated to represent main plant units, such ...
Shape optimisation of continuum structures via evolution strategies and fixed grid finite element analysis
(SPRINGERUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2004-01-01)
Evolution strategies (ES) are very robust and general techniques for finding global optima in optimisation problems. As with all evolutionary algorithms, ES apply evolutionary operators and select the most fit from a set ...
Robust model predictive control of Wiener systems
(Taylor & Francis Ltd, 2011-03-18)
Block-oriented models (BOMs) have shown to be appealing and efficient as nonlinear representations for many applications. They are at the same time valid and simple models in a more extensive region than time-invariant ...
