Information
Optimal Control for a Continuously Stirred Tank Reactor
Introduction
Find an optimal control signal for a continuously stirred tank reactor (CSTR). The temperature in the tank influences a reaction rate, while the temperature in the cooling jacket acts as a control signal. The goal is to go from one concentration to another as quickly as possible, while obeying safety limitations in temperature.
In order to get the full experience of this example, you need the following:
- A desktop Wolfram Language product; a free trial download is available at www.wolfram.com/mathematica/trial/
- The ChemicalTankReactor.nb notebook that came in the same bundle as this model
These pages show an overview of the example. For the full example, open the accompanying notebook ChemicalTankReactor.nb.
Optimal Control
Using the Wolfram Language, find an optimal control signal for the cooling temperature to go from one concentration to another.
Interactive Control
The Wolfram Language also makes it easy to create an interactive interface to see how the system reacts for different signals with simple drag and drop. Interact with this in the accompanying notebook.
