要約(英語): In this paper, a novel approach of right coprime factorization for nonlinear system has been proposed so as to enhance the robustness of the system towards uncertainty. To be specific, different from previous research in which uncertainty of the objective system was regarded to be added as a part of the output, in this work, from the perspective of dilation, the existence of uncertainty is considered as an additional operator inserted into the target plant. As a result, a new robust condition, namely, a time-varying Bezout Identity is obtained. Moreover, given the results of simulation of two numerical examples, the new approach is proved to be effective on the elimination of influence caused by undesired uncertainty.
