How PID Autotuning Works

To use PID autotuning, configure and deploy one of the PID autotuner blocks, Closed-Loop PID Autotuner or Open-Loop PID Autotuner.

Jun 09, 2016 I finally got it to work, you have to heat your bed withing 10 degrees of your target temperature then run the pid autotune, then it will work, as long as you have the pid autotune enabled in your marlin code and that other option below it commented out you are good to go, try that and let me know if it worked for you, if you haven't already figured it out.
This probably would not be ideal for you since you state, 'putting the system in oscillation even as a part of auto-tuning is not acceptable to the users'. Our system would most certainly oscillate and do other horrible things while it was auto-tuning. However, you could run two copies of the PID controller.
Welcome to the TH3D P.I.D. Auto Tuning Guide! This will take you through the steps to P.I.D. Tune your printers hotend. If you have the new Unified Firmware you can go to Control Temperature PID Autotune Then set to 240 if you have a stock hotend and 250 if you have an all metal.

Autotuning Process

3D printing guides – Using Marlin’s PID autotune. 2014-03-25 tom. They determine how much power to send to the heaters by looking at how large the difference between the actual temperature and the setpoint is, how long the actual temperature has been off from from the setpoint and how quickly the temperature is changing at.

The PID autotuner blocks work by performing a frequency-response estimation experiment. The blocks inject test signals into your plant and tune PID gains based on an estimated frequency response.

The following schematic diagram illustrates generally how a PID autotuner block fits into a control system.

Until the autotuning process begins, the autotuner block relays the control signal directly from u to the plant input at u+Δu. In that state, the module has no effect on the performance of your system.

Whereas sustained notes protect their delicate pitch variations for probably the most pure, life like pitch correction.

When the autotuning process begins, the block injects a test signal at u out to collect plant input-output data and estimate frequency response in real time.

If you use the Open-Loop PID Autotuner block, the block opens the feedback loop between u and u+Δu for the duration of the estimation experiment. It injects into u+Δu a superposition of sinusoidal signals at frequencies [1/3, 1, 3, 10]ω_c, where ω_c is your specified target bandwidth for tuning. For nonintegrating plants, the block can also inject a step signal to estimate the plant DC gain. All test signals are injected on top of the nominal plant input, which is the value of the signal at u when the experiment begins.
If you use the Closed-Loop PID Autotuner block, the plant remains under control of the PID controller with its current gains during the experiment. Closed-loop tuning uses sinusoidal test signals at the frequencies [1/10,1/3, 1, 3, 10]ω_c.

When the experiment ends, the block uses the estimated frequency response to compute PID gains. The tuning algorithm aims to balance performance and robustness while achieving the control bandwidth and phase margin that you specify. You can configure logic to transfer the tuned gains from the block to your PID controller, allowing you to validate closed-loop performance in real time.
