transfer function of order four

Hello, I have a question about the use of simulink. It turns out that I have a system with four outputs and one of these four outputs is being controlled. However, I would like to know how I can see the behavior of the other outputs that are not being controlled while I control one of the four outputs. For this development I am using a transfer function.

Hi @Camilo Mahnert Cataldo

Can you insert the image of the Simulink model as well as the mathematical model of the 4th-order system?

It is unknown whether the other three outputs are the states of the 4th-order system , or the time derivatives of the output , , .

Hi @Camilo Mahnert Cataldo,

To observe the behavior of the outputs that are not being directly controlled in a Simulink model, you can use the Scope block or add additional output ports to your transfer function block. Here's how you can achieve this:

1. Using the Scope block:

- Add a Scope block to your Simulink model. You can find it in the Simulink Library Browser under "Sinks".

- Connect the outputs you want to observe to the Scope block.

- Run the simulation and open the Scope block to visualize the behavior of the outputs.

2. Adding additional output ports to the transfer function block:

- Double-click on the transfer function block in your Simulink model.

- In the block parameters dialog, increase the number of output ports to match the number of outputs you want to observe.

- Connect the additional output ports to the desired signals in your model.

- Run the simulation and observe the outputs using the output ports.

Both methods allow you to monitor the behavior of the outputs that are not being directly controlled while controlling one of the outputs. Choose the method that suits your needs and the complexity of your model.
