• Resumen

  • This paper investigates the global adaptive control problem for a class of general switched uncertain nonlinear systems. By improving the well-known mode-dependent average dwell time (MDADT) method, a new adaptive control scheme is established which ensures the global boundedness of all signals in the resulting closed-loop system under a class of switching signals with MDADT property. As an application, the developed control scheme is utilized to solve the adaptive tracking control problem for a class of switched uncertain lower triangular nonlinear systems with unmodeled dynamics. Finally, simulation study is provided for verifying the validity of our results.
