| Abstract: | We investigate the constraint robust output regulation problem for uncertain nonlinear systems. It is assumed that the control direction is unknown, and furthermore, the controlled output is required to be confined in some given region when it approaches zero. Based on the general output regulation framework, a feedback controller is designed by combining the barrier Lyapunov function and Nussbaum-type techniques. Simulation shows the effectiveness of the control scheme and indicates the superiority of barrier Lyapunov function design. |
