Design scheme for nonlinear feedback system using right coprime factorization

摘要

The design and control for the nonlinear feedback system is considered by using operator-based right coprime factorization method, by which there exist some cases that the factor D is difficult to be obtained since the factor D-1 is high nonlinear which renders the verification of the Bezout identity KN + QD = M to be a painstaking process, where K and Q-1 is respectively the feedback and feedforward controller while N is a right factor and M is a unimodular operator, therefore, a sufficient condition is proposed to overcome this problem. A simulation is given to show the effectiveness of the proposed method.
