AI Technical Summary
When dealing with the inability to collect data on the internal state of the tanks and the impact of unknown noise disturbances, the performance of the four-tank chemical system degrades, and it becomes difficult to effectively coordinate network bandwidth utilization and achieve optimal convergence of the state.
A mathematical model is established using the inverse Laplace transform. A dynamic event-triggered control method is designed by combining an observer with H∞ control. The observer suppresses disturbances, and the H2 performance index is used to optimize network transmission resources to achieve threshold scheduling.
In a multi-disturbance environment, the system effectively utilizes limited network bandwidth resources to achieve robustness and asymptotic convergence of state observation, thereby improving the system's control performance.
