Example1.Analysis.NonlinSimulationsMultipleInputs

Example nonlinear time simulations with different input signals

Information

This package contains different models that show how to provide inputs signals to drive the non-linear model being simulated.

The main model used for the identification and verification experiments as in Figs. 6 and 10 in [2] is:

Example1.Analysis.NonlinSimulationsMultipleInputs.A_randomload_and_lowimpactmultisine

It is configured to simulate the default PSS control design with and sec. To change the control design, click on the "Plant" block and enter a new set of parameters. In [2], the two other PSS designs have parameters:

• Re-design 1 obtained using has parameters and sec.
• Re-design 2 obtained using has parameters and sec.

The other models are variants where inputs are set to zero when compared to the case above. They are useful to compare against the above model, for example, the simulation of model "B_noise_..." can be compared to the one above to understand the impact of the input signal compared to only the random noise of the loads, etc. See the "Package Contents" below for information on each case.

In addition, to perform run any simulation and plot the following function is provided: simulate_and_plot

Package Content

Name	Description
simulate_and_plot	Run and plot the simulation used for identification and controller verification.
A_randomload_and_lowimpactmultisine	Main model used for the identification and verification experiments as in Figs. 6 and 10 in [2].
B_randomload_and_loaddisturbance	Same as "A_" above, but removing the input signal for identification.
C_randomload	Same as "B_" above, but removing the load disturbance.
D_loaddisturbance	Same as "B_" above, but removing the random load.
E_no_noise_no_inputs	Used to test the "Plant" block with constant (zero) inputs.

Example1.Analysis.NonlinSimulationsMultipleInputs.simulate_and_plot

Run and plot the simulation used for identification and controller verification.

Information

Usage

1. In the Package Browser, right click on the function and select "Call function...". This will open the function's window.



2. Modify the input string "modelname" by entering any of the other model names within quotes, for example, to simulate the second model in this package, insert the string: "Example1.Analysis.NonlinSimulationsMultipleInputs.B_randomload_and_loaddisturbance", note that the quotes have to be included. Leave the default parameters on first use.
3. Go to the bottom of the window and click on "Execute".
4. Go back to the function's own window and click on "Close".

Sample Output

Executing the function will result in the following plots.
