Robust output tracking control for nonlinear systems using right coprime factorization

This paper deals with an operator based on plant output tracking design problem of time-delays nonlinear systems by using a robust right coprime factorization approach. In details, operator based nonlinear control systems are designed, and sufficient conditions for the designed feedback control systems are obtained. Based on the conditions, robust stability of the nonlinear systems is ensured and output tracking performance is also realized. A simulation example is given to support the proposed design scheme.
