What is a PID Controller? What do the PID terms do?
youtube.com/watch?v=q5VtSrJ3oVQ
---
0:00 - Learning PID tuning from the MASTER
3:00 - What are PIDs?
My video about "what are PIDs" is: youtu.be/q5VtSrJ3oVQ
4:17 - Make sure the drone is mechanically sound
5:42 - Check CPU%
7:00 - RC Link Preset
9:17 - Enable Bidirectional DSHOT
9:44 - Configure Blackbox Options
15:29 - Erase Dataflash (if you have it)
15:45 - Download and install PIDToolbox
Download PIDToolbox from: patreon.com/ThePIDtoolboxGuy
16:34 - Steady Hover
17:54 - Download the Blackbox Data
20:10 - Open the Spectrogram View
25:13 - Evaluate the health of the hover test
34:48 - What's a "good" baseline noise level?
37:10 - ESC PWM Frequency Affects Noise
37:44 - Excess filtering causes delay
39:45 - Adjust the gyro RPM filter
41:51 - Should you turn off gyro lowpass 1?
42:52 - Should you adjust the gyro and d term lowpass?
45:53 - Why we do a "wobble" to PID tune
48:10 - Adjust iTerm Relax
49:44 - What is Dynamic Damping
50:27 - The P/D Ratio
51:56 - PID slider changes BEFORE you tune
52:47 - The first wobble test
56:15 - Custom rates for tuning
58:16 - Opening the results
1:03:57 - Zero I term causes the line to "fall off" at the end
1:04:37 - Use Y-correction to align the graphs
1:06:16 - What about different weight on pitch vs. roll?
1:07:35 - Adjusting PIDs for round 2
1:09:43 - Riaisng I term helped. Pitch is more similar to Roll.
1:10:56 - How hard should you work to match pitch = roll
1:13:41 - Wobble Test #3
1:14:15 - Analyzing Step Response Latency
1:17:29 - Why does yaw look like garbage
1:18:26 - What would excess D look like
1:20:31 - Once P/D ratio is correct, adjust Master Multiplier
1:23:07 - Wobble Test #4
1:26:57 - What does Master Multiplier too high look like
1:28:44 - Should we raise I gain even though tracking is good
1:31:03 - Effect of battery voltage on PID tuning
1:33:13 - Continuing to increase Master Multiplier
1:35:44 - Re-assessing filters
1:37:41 - Analyzing filter latency
1:41:31 - Did the newer battery make step response better
1:41:49 - Do we need to adjust D term filtering more
1:43:55 - How far can we push I gain
1:45:13 - Continuing to optimize I gain
1:49:59 - Let's talk about Feed Forward
1:52:39 - What's the sign of excess FF
1:54:47 - Step Response doesn't work with FF
1:55:21 - FF made my motors HOTTTT
1:57:19 - Analyzing the results of the FF test
1:58:57 - FF in the step response graph
2:02:20 - What is Dynamic D / Dmax
2:04:13 - How to adjust Dmax
2:07:17 - Should you boost Yaw D?
2:08:16 - The before-and-after flights
