Possibilities to simulate control systems can be very useful. During the development of a control system, simulations can verify that the implemented algorithms work as expected. Smaller parts of the implementation can be tested before they are put together to a complete control system. In an existing plant simulation can be used for optimization of the control system and control parameters can be tuned without affecting the real process.
The main goal with this master thesis was to investigate if it was possible to establish communication between the Advant Control Builder and Matlab/Simulink. If that was possible it then were to be implemented in C++ code. We found it possible and have done a Gateway program that establishes the communication between the Advant Control Builder and Matlab/Simulink. To get the values continuously all the way to a running simulation in Simulink we also implemented some S-functions for reading and writing data in Simulink. The communication from the Advant Control Builder is handled with COM/DCOM and an OPCserver. We used an OPC-server developed by ABB. The Gateway that we have implemented handles five connections at each way. It is possible to add more connections but it requires quite a lot of changes in the code. We limited the number of connections to five in the beginning because we needed to have a limitation and thought that it was a good start to test how it worked. The question of how many connections that are possible and realistic did arise but we did not have time to investigate it. The communication between the Gateway and the OPC-server works satisfactory. Since we had to suspend the simulation in Simulink once every sample period, the communication between the Gateway and Matlab is blocked and this causes the communication to be too slow. A reason why we have not solved this problem is that we did not realize that the Matlab thread was suspended until the final phase of the thesis.
