The problem with the Anti-Windup algorithm.

There are some warnings and errors that appeared when I was trying to create 1 Anti-Windup algorithm for the PID controller.

Hi Bao Ngyuyen,

It appears that your Simulink model is encountering an error due to the presence of algebraic loops. Algebraic loops occur when there is a circular dependency of signals between blocks without any delay elements, creating a situation where the output of a block directly or indirectly depends on its own input within the same simulation time step.

To help you understand the specific issue in your model, I have highlighted one of the algebraic loops below:

To address these issues, I suggest reviewing the following resources, which provide comprehensive guidance on identifying and resolving algebraic loops in Simulink models:

1. What are algebraic loops in Simulink and how do I solve them? - https://www.mathworks.com/matlabcentral/answers/95310-what-are-algebraic-loops-in-simulink-and-how-do-i-solve-them
2. Identify Algebraic Loops in Your Model - https://www.mathworks.com/help/simulink/ug/identify-algebraic-loops-in-your-model.html
3. Remove Algebraic Loops - https://www.mathworks.com/help/simulink/ug/remove-algebraic-loops.html

Hope this helps!
