Abstract
In this paper, an event-triggered mechanism for a class of multi-thread control systems is designed by the relationship between the threshold line and the Lyapunov function and an algorithm is proposed with update delays considered. In order to solve the problem of resource waste in complex systems with mismatched characteristics of the number of controllers and controlled plants, a stable multi-thread control algorithm considering the delay is designed by adopting the event-triggered mechanism. In the algorithm, the concept of a novel multi-thread control system is utilized to eliminate the need for a complex description of this class of systems. By reducing the constraints on the Lyapunov function in the traditional switching control scheme, a novel event-triggered rule is designed to save resources and ensure that the system is asymptotically stable. Furthermore, it is proved that the proposed multi-thread control algorithm based on event-triggered mechanism is feasible when the system has a non-zero update delay. Finally, the system is guaranteed to avoid the Zeno phenomenon and the proposed algorithm is investigated by simulation.
