problem with position control

hi, below attach is my simulink for my position control of the quadcopter.it suppose to control my eular angle to get my quadcopter to my desire position.<ATT_quat_WB> is the sensor reading for row,pich and yaw current angle while <POS_R_W> is the sensor reading for the current position .is there any problem with it because my quadcopter go haywire.this is a link to a video of how my quadcopter behave.http://youtu.be/0YoQ1YCSjSomy pid value…See More

"Is your yaw P 0.7 or -0.7? Drifting is normal in stabilize mode.  Scan the forum for auto trim set and follow those directions.  Basically you trim the pitch/roll sticks so that the copter quits drifting.  Then you tell the APM to…"

"hi, i have added value to i and d. my quadcopter stop spinning but the quadcopter still tend to drift. below attach is my angle of att for row, pitch and yaw after 1 min. while my psi and phi is at 0. my theta is not at 0. why is this so when i use…"

pid value

below is a link for my quadcopter simulation.http://youtu.be/8xYpy0YkA-cmy pid value for the roll and pitch is p=0.7,i=0,d=0.1 while for yaw is p=0.2,i=0,d=0.can anyone advice me on why my quadcopter can't stabilise and keep spinning in a cw direction and tend to drift away from the starting point.is it because my pid value is wrong?See More
