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.
Hope this helps!
