State Space plant inversion not implemented #939

It would be great if we can invert a state space with python-control.

The formulation is easy:

The relevant Matlab page is here:

    1. case D<>0 and D is invertible:
      The first case is already wrapped into Slycot.

    1. case D==0 or D is not invertible:
      For the descriptor case, there is a SLICOT subroutine:
      AG07BD.f

    This is not yet wrapped into Slycot.

    As far as I know, neither Scipy nor Python-Control can handle descriptor systems.
