Description: In this article, we present an event-triggered control law for systems with an unknown control direction, where the adaptation dynamics of the Nussbaum gain are sampled. Specifically, we employ the emulation method and introduce a specific set of sampling errors. This approach enables the design of an event-triggered law without encountering Zeno behavior. Additionally, we introduce a lemma to address the non-integrability issue of the Nussbaum gain dynamics during the event-triggered law design. We apply this design philosophy to co-design both the continuous-time controller and the event-triggered law, aiming to achieve the global stabilization of systems with an unknown control direction. Finally, we validate the theoretical results through a numerical example.
