Sensitivity of operator based nonlinear feedback control design using robust right coprime factorization

In this paper, sensitivity of operator based nonlinear feedback control systems is considered. To stabilize the nonlinear systems, controllers are designed by using a condition of robust right coprime factorization. Further, for guaranteeing the stabilized systems insensitive to the perturbations, a new condition is proposed. The effectiveness of the proposed condition is verified by numerical simulation results.
