Abstract :
The definition of a state vector which takes into account the error functions of a nonlinear discrete multivariable plant allows one to obtain an estimate of the forced motions by utilising a characteristic property of the autonomous system. The result generalises that of Iwens and Bergen* obtained for monovariable plants via the discrete analogue of Popov´s global-stability criterion.
