Inner Product-based Robust Right Coprime Factorization for Nonlinear Control Systems Design

摘要

This paper deals with a class of nonlinear systems with unknown bounded perturbations. In detail, first, an operator is defined based on the inner product of Hilbert spaces. Based on the proposed operator, robust right coprime factorization is obtained. Second, robust stability of the nonlinear system with unknown bounded perturbations is guaranteed using a rational number boundary. Finally, a numerical simulation is given to confirm the effectiveness of the proposed method.
