A Test for Differential Flatness by Reduction to Single Input Systems [PDF]

open access: yes, 1995
For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.
