See end of file for installation and use instructions. Contents of this Zip archive: ADCHEM15_0010.pdf A paper submitted to ADCHEM 2015 providing details and describing advantages of the modified code. temexd_mod.c C source code for compiling TEMEX mex file. Note that this version requires the disturbance flags to be input signals, not parameters. Thus, they can change with time. See comments at the beginning of the source code for details of model requirements and options. teprob_mod.h C header file needed when compiling. temexd_mod.mexw*** Mex file ready for use on a Windows ***-bit system. It was compiled using the MATLAB mex command with the Microsoft Visual Studio 2013 c compiler and tested in MATLAB/Simulink release R2014b. R12_Example.m MATLAB test script that runs the plant in an open-loop manner. tesys.mdl Open-loop Simulink model called by R12_ExampleScript.m. teplot.m Script that plots the results at the end of some simulations. MultiLoop_mode1.mdl Simulink model of the control strategy described in "Decentralized control of the Tennessee Eastman Challenge Process", N. L. Ricker, J. Proc. Cont., Vol. 6, No. 4, pp. 205-221, 1996. It is set up to initialize and run with constant setpoints at the "Mode 1" operating condition. NOTE: override loops are not included. The .mdl file calls two custom scripts (lines 34 and 35): PreLoadFcn "Mode_1_Init" StopFcn "TEplot" These initialize the simulation variables and plot the results at the end of the run. See the files "Mode_1_Init.m" and "TEplot.m" for more details. MultiLoop_mode3.mdl Similar to MultiLoop_mode1.mdl, but designed to run at Mode 3 conditions. Includes an additional override that reduces the recycle valve % open when the separator coolant valve goes above 90%. If this is not included, the coolant valve saturates and the system loses control of reactor level. MultiLoop_Skoge_mode1.mdl Similar to above, but uses the control strategy described in "Self-Optimizing control of a large-scale plant: the Tennessee Eastman process" Larsson, T., et al., Ind. Eng. Chem. Res., Vol. 40, pp. 4889-4901, 2001. It automatically runs "Skoge_Mode1_Init.m" and "TEplot.m". Mode_1_Init.m Script file executed automatically when you run "MultiLoop_mode1.mdl". Mode_3_Init.m Script file executed automatically when you run "MultiLoop_mode3.mdl". Skoge_Mode1_Init.m As above, but for "MultiLoop_Skoge_mode1.mdl". Mode1xInitial.mat Contains initial conditions for "MultiLoop_model.mdl". It is loaded by the script file "Mode_1_Init.m", which is executed automatically when "MultiLoop_model.mdl" is opened. Mode3xInitial.mat Contains initial conditions for "MultiLoop_mode3.mdl". It is loaded by the script file "Mode_3_Init.m", which is executed automatically when "MultiLoop_mode3.mdl" is opened. Mode1SkogeInit.mat As above, but for "MultiLoop_Skoge_mode1.mdl". TElib.mdl A Simulink library containing two controller blocks. These are used in the two "MultiLoop" simulations. System Requirements: Tested using MATLAB/Simulink release R2014b. Extent of compatibility with older releases is unknown. Installation: 1) Unzip the archive into a new directory. 2) Start MATLAB and make the above new directory the default. 3) If your system is other than a Windows ***-bit machine, you will need to use the MATLAB mex command to compile the C source code and create a mex file. See instructions at the beginning of the C source code. In order to run the simulation examples, the mex function must be named temexd_mod. NOTE: the code contains ~4000 lines and may take several minutes to compile. Testing the code: 4) Try running the R12_ExampleScript.m file. This illustrates a situation in which the plant is running open-loop. The specified simulation time is 5 hours but at about 1 hour the plant, which is open-loop unstable, exceeds the maximum reactor pressure and the simulation terminates automatically. Plots show transients of some key variables. If this works, your installation should be OK. 5) Try running one of the closed-loop models. If you get a "file not found" or "variable undefined" error from MATLAB, make sure the initialization scripts described above are on the MATLAB path. The simplest approach is to put all of the files in a single directory and make it the MATLAB default directory. Mode_3_Init.m Initial model states needed for the above. Mode3xInitial.mat Contains initial conditions for "MultiLoop_mode3.mdl". It is loaded by the script file "Mode_3_Init.m", which is executed automatically when the model is opened.
