Abstract :
This paper presents a method for the analysis and control design of nonlinear systems in the presence of actuator saturation. The system under consideration is subject to input saturation. Hence, we design a control law v by adapting backstepping technique. Following, we give a region, such that v les 1 in the region. We can ensure stability of the saturated closed-loop system based on the use of a suitable Lyapunov function.
