Abstract :
It is proved that a discrete-time nonlinear system in a strict feedforward form is state equivalent to a string of forward shifts. An algorithm-based checkable necessary and sufficient conditions for a discrete-time nonlinear system to be transformable into a strict feedforward form are given. Moreover, sufficient conditions for an accessible system to be transformable via static state feedback to the feedforward form are given.
