Multimode dataset of Tennessee Eastman v1.0

Background

Tennessee Eastman (TE) model Is an important tool in all disciplines of systems theory, for comparative studies or validation of algorithms. Its strength is that it is based on real process modeling. This leads to a rather complex nonlinear model of a multi-component system. Due to the frequent use of the model, it is very beneficial that this model, or more precisely its code, works flawlessly [1]. On this basis, a revision and extension of TE process model is proposed and is shown in Fig. 1.

Usage

• If you want to use the datasets in the project, you can download them directly by using Python or Matlab.

• Example (Normal data of mode 1):

  1. Python

  import scipy.io as scio
  
  data00 = scio.loadmat('xxx/TEP_multimode/temexd_mod/M1/m1d00')['m1d00']
  
  data00_X = data00[:,:53]
  
  data00_Y = data00[:,53:]
  

  2. Matlab

  load xxx/TEP_multimode/temexd_mod/M1/m1d00
  
  data00_X = m1d00(:,1:53)
  
  data00_Y = m1d00(:,53:81)
  

• If you want to regenerate the dataset, you can run MultiLoop_mode1.mdl to MultiLoop_mode6.mdl.

Dataset Introduction

We have made six modes of datasets in 72 hours, and there are 28 faults in every mode. All of them contain 12 variables of input, 41 variables of measurement, and 28 variables of disturbance. The adjusted parameters are saved in Mode1xInitial.mat —Mode6xInitial.mat. The parameters of different modes are listed in Fig. 2 and Fig. 3. The process disturbances are shown in Fig. 4 ( Datasets m（1-6）d01-28.mat correspond to disturbance types IDV(28)-(01) respectively).

Adjustment of mode

• Users can adjust parameters to achieve different modes by themselves.

• Example (mode 2)

  1. Copy files Mode_1_Init.m, Mode1xInitial.mat and MultiLoop_mode1.mdl and rename to Mode_2_Init.m, Mode2xInitial.mat and MultiLoop_mode2.mdl.

  2. Modify Mode1xInitial in 29 lines in Mode_2_Init.m to Mode2xInitial.

  3. Modify Mode_1_Init to Mode_2_Init by opening MultiLoop_mode2.mdl and the steps as follow figures:

  

  

  4. Running upda.m and modify as follows:

     clear all;
     clc;
     load Mode2xInitial
     for i =1:35
         blockName = xInitial.signals(i).blockName;
         blockName(15) = '2';
         xInitial.signals(i).blockName = blockName;
     end
     save ('Mode2xInitial.mat','xInitial')
     

  5. Adjust the parameters MultiLoop_mode2.mdl according to Fig. 2 and Fig. 3. Note that the value of parameters adjusted each time should not be too large, otherwise the simulation will end quickly. And run the following code after each successful adjustment.

     xInitial = xFinal
     

  6. All parameters are adjusted to the final mode and run:

     save('Mode2xInitial.mat','xInitial')
     

Mode

We selected normal data under six modes for display, as shown in Fig. 5.
