英文摘要：

This paper introduces some concepts, theories and applications of operator-based robust right coprime fac-torization （RRCF） approach, which is a small new method in robust nonlinear control field. In details, the origin and basic concepts of this approach is introduced firstly. Then, the system designs o11 robust stability, tracking performance and fault detection using the operator-theory-based approach are discussed. Finally, the applications of this method in engineering are shown to validate its effectiveness.
