Abstract :
The concept and theory of the p th-order inverse of a nonlinear system es developed in this article. The p th-order inverse, K_{(p)}^{-1} , of a system H is defined as a system for which the Volterra series of the system Q formed by the tandem connection of K_{(p)}^{-1} and H is Q[x]= x+ \\Sigma _{n=p+1}^{\\infty } Q_{n}[x] so that the 2nd through the p th-order Volterra operators of Q are zero. The necessary and sufficient conditions for the existence of K_{(p)}^{-1} are determined. It is shown that the p th-order pre-inverse of a system H is identical to its p th-order post-inverse. In addition, a synthesis of K_{(p)}^{-1} is obtained. The p th-order inverse offers an approach to the study of the system inverse, H^{-1} , since, as p \\rightarrow \\infty , K_{(p)}^{-1} becomes the Volterra series of H^{-1} . This approach is discussed and some applications with regard to nonlinear differential equations and nonlinear feedback systems are presented.
