| Abstract: |
| This talk presents a resilient event-triggered load frequency control (LFC) scheme for multi-area power systems under DoS attacks, using only input-output data. Unlike existing methods that rely on average dwell time, we directly analyze how attack patterns interact with event-triggered mechanisms. This allows us to distinguish valid and invalid time intervals within attack periods that truly affect system dynamics. Based on this, we propose an attack compensation recovery strategy within a model-free adaptive control framework, where both the controller and parameter estimator are reconstructed using the last successfully transmitted signal before an attack. A recursive analysis then gives a sufficient condition for tracking error boundedness, linking stability to the ratio of valid to invalid time during attacks. Simulations on multi-area power systems validate the effectiveness of the approach. |
