A DJ,Computer Engineer,Multicopter Programmer

Please tell us a bit about your UAV interest

as a university graduation project i choose quadrotor. I made everything by my self from chasis to software. from that day on i am working on these things as a hobby

Baris replied to OSAMA SARAFARZ's discussion Accelerometer sensor gravity compensation.
"basicly convert your imu readings to quaternion  then
gx, gy, gz represents gravity in x, y and z axis respectively

gx = 2 * (q1 * q3 - q0 * q2); gy = 2 * (q0 * q1 + q2 * q3); gz = q0 * q0 - q1 * q1 - q2 * q2 + q3 * q3;

the result of gx gy and gz…"

Baris commented on leonardthall's blog post ArduCopter 2.9 PID Loops for STABILIZE, ACRO and ALT_HOLD
"Hi Leonard,
From the PID schematics I understand that D term in acceleration is calculated from error which means it causes derivative kick when you change the setpoint. so how you are handling this derivative kick issue"

I am developing my own autopilot system with arduino Mega 2560 i added most features that the arducopter has like gps position hold, waypoint, point of interest but the thing that i cant be success is altitude hold. I am usning Bosch BMP085…

Baris replied to Alex O.'s discussion What PID parameters do DJI settings correspond to in APM Code?
"I am not sure but I think they are not using PID algorithm for control may be they are using LQR controller or Sliding Mode controller. I am not sure about their performance but I think all these performs better than PID. May be thats why they have…"
