Reason for QP_failure trackable?

Hi everyone,

i’m wondering if it is possible the track the reason for the failure of the QP solver when using acados in matlab. Now using RTI, I only get 4 if the QP fails. But what i’d also like to have is the reason for the failure like ‘Problem is infeasible’ or ‘System is unstable’ etc. so that I know whether I should adjust the system equations and constraints or change the solver configuration to reduce the failure of the QP.

Thanks a lot

Hi,

you can also get the QP solver status from acados.
The meaning of the QP solver status values depends on the solver and can be looked up in the specific QP solver code.

Hi Frey,

thanks for your reply. Could you show me with an example where I can find it?

Which QP solver are you using?
