Kalman filtration for rotation

I want to use Kalman filter for rotation. I have rotation matrix, but i can't use filtration for it, because all it's elements interdependent. That's why i try to convert matrix to euler angles and to filter each of compoments.

My questions:

is this filtering of euler angles will be right? (is all components x, y, z independent? I think no) If yes, how to avoid gimbal lock during filtration?
is there a better way to filter the rotation?

Hi, to avoid gimbal lock you can use Quaternions instead of euler angles. For example, Quaternions are widely used in robotics to represent rotations.

Thank you, i know this, but quaternion components also interdependent. I found this article (http://www.malcolmdshuster.com/pub_1993f_c_qnorm_mds.pdf), maybe it will be helpful for me but i hoped to find the easyest solution
