Water Level in Tanks 1 and 2 Data

Model the height in Tank 2 using the data provided in Sect. E. 1 Water Level in Tanks 1 and 2 Data. 

Take a process that you are familiar with and design an experiment to identify the process. If possible perform the experiment and obtain an appropriate model of the system. Make sure to clearly explain the design of experiment, model creation, and model validation used. Consider both linear and nonlinear modelling. 

This section gives detailed information about the data set used for analysis in Chap. 6. All data can be downloaded as an Excel spreadsheet or MATLAB file from the book website. 

The water level in both Tanks 1 and 2, as well as the corresponding pump flow rates, is presented in Table 6.3, in 15 s intervals.

The data obtained for both Tank 1 and Tank 2 levels is shown in Fig. 6.10. A total of 2 h of data were collected. It can be seen that there are no obvious issues with the data collected, such as missing values or abnormal values. In order to use the data, it is necessary to downsample the 1 s data to the desired sampling rate of 15 s. This can be accomplished by taking every 15th data point from the original data set for the new downsampled data vector. The downsampled data are presented in Sect. 3.A.1 Water Level in Tanks 1 and 2 Data.
