Sliding-Mode Control of a Class of Nonlinear Systems in the Presence of Input Saturation

摘要：

　　In this paper,we present a sliding-mode control approach for a two-order nonlinear system in the presence of input saturation and external disturbance.A robust control algorithm is constructed by using backstepping design techniques.Two well-defined smooth functions are introduced to approximate the primary functions so that they could be differential.To overcome the problem of input saturation,a new auxiliary design system and a Nussbaum function are incorporated into the control method.It is proved that the global stability of the closed-loop system can be guaranteed by the proposed control algorithm.A simulation example is included at last.
