    PID tuning, too slow to stabilize and overshooting

    Hi, thank you for putting me one the right track :D I finally got it flying \o/ In the case someone have the same problem in the future, I was integrating my PID output over time instead of outputting it directly to the motors (yeah, was a bit stupid..) Still need to slightly tweak filters and...

    PID tuning, too slow to stabilize and overshooting

    Erf sorry I was talking about attitude, no 'L' involved :D. About altitude, yes, the only thing that controls it is the throttle. My thread is about stabilizing, I'm actually trying to get stable hovering. I think that at the current state, it could fly with a stabilization amplitude of several...

    PID tuning, too slow to stabilize and overshooting

    I'm using an EKF to filter noise of accelerometer, gyro and magnetometer. Then, I use a simple complementary filter to convert filtered values to roll/pitch/yaw, and finally my PID simply controls the motors to adjust the drone's attitude. Am I missing something in this processing chain ? The...

    PID tuning, too slow to stabilize and overshooting

    Hello, I'm building my very first quadcopter totally from scratch, using a Lynxmotion mini V-Tail frame, and motors from the same brand. My controller board is a raspberry pi with software that I wrote entirely by myself, with a fixed update rate at approximately 100Hz. I'm using an Invensense...
