Micchal, i not see any MAX_ERROR limit in int_quat algorithm.
I only see this on euler_int.

i do some tests and the same behavior occur here.
BTW, i think this behavior never occur inflight because the error are corrected with values much less than 10000.

Hi guys,

I am running a quadrotor with the default aiframe config file (quadrotor_lisa_m_2_pwm_spektrum.xml), master branch, stabilization = int_quat, ahrs=int_cmpl_quat, Lia 1.1 with Aspirin 2.2.

I did the test on a testbench, and the integrator doesn't seem to work properly. Instead of just saturating at the MAX_ERR limit, it jumps up and down even though the error between set point and actual attitude is constant.

Look at the logs, my guess is that the problem will most likely be on these lines:

What do you think?
