Hi David,
I understand that you are not able to find a dataset which meets your requirement.
One dataset that you can use for modelling a non-linear system, such as cascades tank, is the "TwoTankSystem" dataset available in MATLAB's Control System Toolbox. This dataset represents a non-linear cascaded tank system and can be used for system identification and control purposes.
To load the "TwoTankSystem" dataset in MATLAB, follow these steps:
- Make sure you have the Control System Toolbox installed.
- Open MATLAB and navigate to the MATLAB Command Window.
- Load the "TwoTankSystem" dataset using the following command:
- load('twotankdata.mat');
This command will load the dataset into your workspace which provides the following variables:
u (input signal): A vector representing the input signal applied to the system.
y (output signal): A vector representing the output signal of the system.
You can also try and simulate a dataset using a mathematical model or by simulation using Matlab or Simulink which represent the behaviour of the cascaded tanks or DTS200 Three Tank system. Following steps can be used for this purpose:
1. Set the desired number of data samples N.
2. Initialize empty arrays to store the input and output data: inputs = [], outputs = [].
3. Define the initial conditions for the system variables (e.g., tank levels, valve positions).
4. For i = 1 to N:
a. Randomly generate an input signal or control action for the system (e.g., valve opening/closing).
b. Apply the input signal to the system and simulate its response for a given time interval.
c. Record the input signal and the corresponding output response.
d. Update the system state variables based on the output response.
e. Store the input and output data in the arrays: inputs[i] = input signal, outputs[i] = output response.
5. Save the input and output data arrays as a dataset.
You can simulate your own dataset using the above steps if the “twotankdata” doesn’t fit your requirement.
