Abstract
This paper researches the problem of controller design for parametric strict-feedback nonlin-ear systems with asymmetric time-varying full state constraints and unknown virtual control coefficient. We can ensure that the asymmetric time-varying constraint are not violated by defining appropriate error variables and introducing time-varying barrier Lyapunov functions (TVABLF)in traditional adaptive back-stepping design procedure.It is also proved that all signals in the closed-loop system are uniformly ulti-mately bounded and the tracking error remains in a bounded compact set.The simulation results illustrate the effectiveness of the proposed control scheme.关键词
