Operator based control design for perturbed nonlinear systems output tracking

In this paper, operator based control design for output tracking of nonlinear systems with perturbation is considered by using robust right coprime factorization. In details, mismatch is derived and a nonlinear control design is proposed, which simplifies the former operator based control design scheme. Based on the proposed design schemes, the system is robustly stable and output tracking performance is realized. Finally, the effectiveness of the proposed design scheme is confirmed by simulation examples.
