This study introduces an event-triggered control for large-scale systems facing cyberattacks and data loss. The new method ensures system stability and performance despite complex network conditions.
Area of Science:
- Control Systems Engineering
- Networked Systems
- Cyber-Physical Systems
Background:
- Large-scale interconnected systems present challenges due to multiple coupling links with varying weights and delays.
- Quantization, packet dropouts, and stochastic deception attacks degrade system performance and stability.
- Distributed control is essential for managing complex, interconnected systems effectively.
Purpose of the Study:
- To develop an event-triggered distributed dynamic output-feedback control (DOFC) approach.
- To achieve dissipative stabilization for large-scale systems under adverse conditions.
- To ensure exponential mean square stability and strict (Q, S, R)-dissipative performance.
Main Methods:
- Construction of an event-triggered distributed dynamic output feedback controller (DOFC).
- Derivation of sufficient conditions for exponential mean square stability and strict (Q, S, R)-dissipative performance.
- Utilization of the cone complementarity linearization (CCL) algorithm to solve a nonlinear minimization problem for control gains.
Main Results:
- Sufficient conditions for the exponential mean square stability and strict (Q, S, R)-dissipative performance were established.
- The proposed event-triggered DOFC approach effectively handles quantization, packet dropouts, and stochastic deception attacks.
- Control gains were successfully determined using the CCL algorithm.
Conclusions:
- The developed event-triggered distributed dynamic output-feedback control strategy is effective for stabilizing complex large-scale systems.
- The approach guarantees stability and performance under challenging conditions including cyberattacks and data imperfections.
- Numerical verification using a continuous stirred tank reactor (CSTR) system validates the theoretical findings.

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
