  • brings process modelling power of gPROMS to control systems design
  • easy transfer of models between process and control engineers
  • allows easy re-use of non linear models such as distillation, or complex reactors
  • full physical property and equilibrium or mass transfer modelling
  • harnesses the advantages of both systems
  • both groups work in their preferred environments

… for integrated process design and control.

The gPROMS® Object for Simulink® (gO:Simulink) is a unique and powerful tool that enables control engineers to use complex non-linear gPROMS advanced process models directly within the Mathworks Simulink and MATLAB® environments.

For example, a detailed dynamic distillation column built for a design study can be embedded as a Simulink block for use in control analysis and design.

This powerful combination of best-in-class technologies is designed to enable control engineers to work in their environment of choice using the detailed gPROMS non-linear Differential-Algebraic Equation (DAE) models built by process engineers during the equipment design.

This helps promote seamless working across different parts of the organisation, unlike other modelling approaches where models need to be simplified and rewritten between environments.

How gO:Simulink works

You can package and export any gPROMS model to Simulink with all the solvers and support software required for its solution.

gO:Simulink then embeds the model in the Simulink flowsheet as a Simulink Block or S-function, where it is executed just like any other Simulink block.

How gO:Simulink works: schematic

A powerful dictionary feature allows replacement of individual gPROMS models – such as control elements – by equivalent Simulink blocks if required.

Using gO:Simulink – a simple step-by-step guide

gO:Simulink step-by-step guide

The gO:Simulink block executes just like any other Simulink block. gO:Simulink automatically takes care of all the mathematical transformations required to convert gPROMS' Integro-Partial Differential-Algebraic Equation (IPDAE) formulation to Simulink's Ordinary Differential Equation (ODE) representation.

This operation is transparent to the user and takes minimal time, yet allows models of virtually any level of complexity to be used within Simulink.

Licensing

gO:Simulink is licensed as a separate PSE product. A gPROMS ModelBuilder licence is required if you wish to build the gPROMS model that will execute within Simulink.
