There are many PI controllers out there, and for certain applications, this is all that is required. I will post a video at the bottom of this article that shows these steps inside the automated PID Simulator to provide a practical example for those (like myself) who are more visual learners.įor the hands on learners, download the PID Simulator app from the Microsoft Store to put these steps into practice! Derivative Once the controller is stable, and responding desirably… congrats! you now have a working PI controller. If the controller starts to oscillate, or become unstable, adjust the I value in the opposite direction until the controller becomes stable again. The goal of tuning the integral value, is to achieve an adequate controller response or reaction time (after the initial response from the proportional is set). Increase the integral gain in small increments, and with each adjustment, change the set point to see how the controller reacts. Always start with small steps when adjusting a PID controller, and give time between each adjustment to see how the controller reacts. Once the proportional value is found, we can start to tune the integral.
