Adaptive finite-time event-triggered command filtered control for nonlinear systems with unknown control directions

In this article, we study an adaptive finite-time event-triggered command filtered control problem based on output feedback for a class of nonstrict-feedback nonlinear systems with unknown directions. Firstly, the continuous functions in are approached by fuzzy logic systems, and coordinate transformations Nussbaum function technique introduced to settle caused directions systems. Then, order reduce communication burden between controller actuator, algorithm is designed means backstepping technique. It proved that tracking observer errors adjusted around zero small neighborhood finite time all signals closed-loop bounded. addition, filtering technology error compensation system fractional power constructed avoid complexity explosion issue design process. Finally, simulation examples included verify availability superiority approach.
