Adaptive event-triggered tracking using nonlinear disturbance observer of arbitrarily switched uncertain nonlinear systems in pure-feedback form

作者:

Highlights:

• A NDO-based event-triggered tracker is developed in the presence of switched nonaffine nonlinearities.

• The same adaptive estimate terms are derived in the control laws and the NDO.

• The stability of the closed-loop system is analyzed mathematically.
