Robust Output Regulation Problem with Prescribed Performance for Nonlinear Strict Feedback Systems

This paper investigates the problem of robust output regulation control with prospected transient property for strict feedback systems. By employing internal model principle, a can be transformed to stabilization new constraint. Then, by constructing speed function and adopting barrier Lyapunov technique, dynamic controller designed not only drive error closed-loop system entering into prescribed performance bound within given finite time, but also achieve that converges zero asymptotically. The effectiveness results is illustrated simulation example.
