Comparison of Iterative Set-point Optimisation Strategies under Structural Plant-model Mismatch
نویسندگان
چکیده
This paper considers the set-point optimisation problem under plant-model mismatch. Three iterative optimisation strategies, the two-step method, the integrated system optimisation and parameter estimation (ISOPE) method and the gradientmodification optimisation method are compared for a nonlinear chromatographic separation process using different structurally mismatched models as nominal process models. The gradient-modification optimisation method is proven to be very attractive when a large structural plant-model mismatch exists. Its ability to deal with disturbances is also shown.

Iterative set-point optimization of batch chromatography
An iterative gradient-modification optimization strategy is applied to the set-point optimization of batch chromatography in presence of a plant-model mismatch. A new method is used to deal with process-dependent constraints. The methods requires the estimation of the gradient of the real process mapping which is computed by a technique which considers the influence of errors and the number of ...
متن کاملOptimisation of an Ammonia Synthesis Loop
A Hysys model representing the steady state behaviour of a Haber-Bosch ammonia plant was developed based on a dynamic model and plant data from Norwegian fertiliser company Yara International ASA. The plant model was optimised using matlabs fmincon function with an interior-point method for economical optimisation with the aim to study the performance of different strategies. The Haber-Bosch am...

متن کاملVelocity Inversion with an Iterative Normal Incidence Point (NIP) Wave Tomography with Model-Based Common Diffraction Surface (CDS) Stack
Normal Incidence Point (NIP) wave tomography inversion has been recently developed to generate a velocity model using Common Reflection Surface (CRS) attributes, which is called the kinematic wavefield attribute. In this paper, we propose to use the model based Common Diffraction Surface (CDS) stack method attributes instead of data driven Common Reflection Surface attributes as an input data p...
متن کاملOn new faster fixed point iterative schemes for contraction operators and comparison of their rate of convergence in convex metric spaces
In this paper we present new iterative algorithms in convex metric spaces. We show that these iterative schemes are convergent to the fixed point of a single-valued contraction operator. Then we make the comparison of their rate of convergence. Additionally, numerical examples for these iteration processes are given.
