Reproducibility in nonlinear systems using dynamic compensation and output feedback

The question of functional reproducibility of multivariable nonlinear systems with unknown initial state is considered. A sufficient condition for the existence of control to generate a given real analytic function as the output of a composite system consisting of a compensator in cascade with a nonlinear plant is derived. A static prefilter (right-inverse system) with only measured output feedback is constructed to generate the required control input to the composite system.
