The Nonlinear Interactor and Its Application to Input-Output Decoupling
The solvability of the input-output decoupling problem via pure dynamic state feedback, a special type of dynamic compensator without zeros at infinity, is investigated. A necessary and sufficient condition for the solvability of this problem is established in terms of a nonlinear interactor, a new concept in the theory of nonlinear control.
