Dynamic Surface Control for a Class of Nonlinear Systems in the Presence of Input Saturation

摘要：

　　In this technical note,we present a novel control approach based on dynamic surface for single input nonlinear systems in the presence of input saturation.The control algorithm is constructed by introducing first-order filtering of the virtual input at each step of the traditional backstepping approach.To deal with the problem of input saturation,we incorporate a new auxiliary design system and Nussbaum gain functions into the control scheme.Compared with the early backstepping approach,the dynamic surface control scheme has greatly simplified the design process.It is proved that the global stability of the closed-loop system can be guaranteed by the proposed control algorithm.
