In this paper, the method and theory of coprime factorizations of nonlinear systems based on the operator theory are introduced. The applications of the method and theory of nonlinear coprime factorizations in the control theory are discussed from all aspects, such as from the existence of the coprime factorizations, the construction of the Youla parameterization, the robust stability, the identification and the design of the observers. The research direction of the coprime factorizations in nonlinear systems in the future is proposed at the end of this paper.
