Hei,

Thanks for your interest and answer. These three differential equations are proper and according to theory I should receive curves like this (see attachment - I apologize you for delay with this).
There are both curves for angular velocity and pure angular. According to theory using above differential equations I should receive similar solution.
Please note I do not have for teta; curves are continious in time (no gaps) - not goog quality of pictures.

There are curves for 

1. For ang
2. For angular velocity (ang)
3. Both for beta and angular velocity (beta)

Many thanks again,

Cezary
