Robust Stabilization of Input-Affine Nonlinear Systems Under Network Constraints

With the advent of event-triggered control, the input-to-state stable (ISS) assumption proved to be a powerful tool in designing triggering rules, especially when dealing with nonlinear systems. In this article, we propose a robust stabilizing event-triggered controller for an input-affine class of nonlinear systems. Rather than relying on the ISS property as a pre-existing condition, we provide sufficient conditions for the ISS condition to hold and then employ the proposed conditions to stabilize the event-triggered system. Moreover, our approach guarantees the isolation of sampling instants in the presence of arbitrary disturbances. Our proposed design covers both emulation and joint design methods. The results are finally validated through a compelling example.
