    Greetings to everyone, I am trying to tune the Kp, Ki, and Kd values for my controller using Matlab. To do this, I need time and amplitude data of the SetPoint and Present Value signals that are being graphed in real-time on the interface.

    I would greatly appreciate it if you could help me understand how to achieve this. I was attempting to create my own controller without constants as a starting point and then obtain a transfer function with the help of Matlab to be able to tune the constant values for the PID controller. I have considerable knowledge in the area of controller tuning, and if I obtain this data, I could contribute to the community with an automatic tuner based on the requested data.

    Greetings, I am making significant progress with the interface in Matlab. For testing, I am using a code where I read an analog port and send the SetPoint through the interface. The data generated can be processed in Matlab to synthesize the proportional, integral, and derivative parameters upload_2024-6-13_20-25-19.png of the controller.

    Does anyone have an idea on how to extract data from the sensor and the target or SetPoint from SMC3Utils?

    PD: My native language is Spanish; I am translating with Google Translate.
