After watching countless PID videos to try and get understanding of PID separately, I can honestly say that your video was by far the most straight forward, easy to understand and straight to the point. Simplicity is key and you did that super well! Thank you so much!

D is watching sudden change of position within the fraction time to give feedback. It does’t matter where the target is. So .. 1. Set P for the smooth and sluggish curve. 2. Set I to help add power to P if it is taking too much time to get to the target. 3. Set D to push the power back if I is doing too much work and excessive acceleration. P I’ll try to get to the target. I I’ll give you extra power because you are taking too much time. D I’ll slow you down because I is giving too much power and detected sudden movement in short period of time.

P term is a rubber band with a resting length of zero. It needs distance to produce tension. If you increase the load on a rubber band, it needs to stretch further in order to produce the correct tension. This is insufficient for a regulator since you expect a regulator to compensate. The I term naturally complements the shortcoming of a rubber band. And since both pull towards the setpoint, you need the D term to compensate to avoid overshoot.

I have to write and say thank you. I built a PID box to control oven temps and I have been screwing with it all day. I knew what I wanted it to do but I just didn't know how to get there. Your explanation of D solved my problems. I was getting a 20 degree over and 10 degree under oscillation. Now I am getting a .1 to .3 degree over oscillation and thats it. It holds at exactly 167.0 to 167.3. Perfect for killing covid-19 on masks gloves whatever. I am using 2 oven thermometers to verify the temp and it is dead nuts. Again thanks so much I hadn't heard D explained that way before and it all clicked when you said it. TAS

Thankfully, most micro controllers now have auto-tune feature. Turn it on and let it do its thing. Your video can be applied to many different control application. Thanks for sharing.

One the best explanation I’ve come across watching quite a lot of PID vids. Still trial and error in tuning goes a long way. Especially if you got a very good updated trend to look at on a short time scale like inn15-30 min span or so. That allows you to see how things are playing out on a trend in adjustment as you try to smooth things out.

Referring to the beginning of the explanation: P term, as i understand it. does not slow down or speed up. That is derivative. P term also does not move back and fourth. That is Integral. The P term tries to move to the target, but because of physics, it ends up being in the wrong place. It outputs proportional to the input. If the p is 2/1, it outputs 2 for every 1. It is one number, the desired destination. Integral and Derivative correct the errors.

I just don't understand. Whenever I see other examples, it shows a high rate of change (approaching set point quick, say a PV of 40degress and set point of 50 degrees)giving D a high value. If we are approaching a set point and want to avoid overshoot, is the D value inverse? So the D value gives a minus value to the PID controller to lower the power to avoid overshoot?

Looking at your dots made me think - hmmm....looks like iteration steps over time......which brings my question: How many times does this process iterate in a single second? I know my loop is set to 8kHz. Is that 8000 times a second? Or is it a higher magnitude, like 8 million? Thanks for the great video. 👍
