IMU integral error #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. in IMUupdate set input for gyro always = 0 (that mean use only accelerometer)
2. run the IMUupdate fast ( 500hz (halfT of 0,001 or 0,002) ) 

What is the expected output? What do you see instead?
the expected output should move only pitch and roll. instead it also move very 
much on yaw.

Solved commenting out integral correction (or setting Ki = 0)

stupid!
  // integral error scaled integral gain
  exInt = exInt + G_Dt * ex * Ki;
  eyInt = eyInt + G_Dt * ey * Ki;
  ezInt = ezInt + G_Dt * ez * Ki;

I'm looking at IMU's code but i can't find G_Dt. What is it?
