I’ve recently been working on PID tuning. The flight performance shown in the attached screenshot is the result after my velocity loop PID parameter adjustment. Could you help evaluate if any parameters still need further modification? The P gain has already been set to its maximum value.
At least post a proper flight log.
Your vehicle’s ability to change linear speed is limited by different factors such as max tilt, motor power, weight, etc. Make sure your setpoints are realistic as well.
All in all - it looks ok. I don’t expect vehicle’s speed to change as rapidly as your setpoints (you’re welcome to calculate the expected acceleration from these inputs, looks high).
Thank you for your suggestions. I have confirmed that the inner loop tuning parameters work perfectly, but the velocity loop performance is unsatisfactory. This may be related to my motor and propeller selection.
