Dynamic Event-Triggered State Observers for a Class of Nonlinear Systems With Time Delays and Disturbances

This brief considers event-triggered robust observers for one-sided Lipschitz systems with time delays and disturbances. We first design a Zeno-free dynamic event-triggered mechanism. Then, based on this mechanism, we design a robust state observer, which ensures that the state estimation vector robustly estimates the state vector of the systems. Two numerical examples and simulation results are provided to illustrate the obtained theoretical results.
