Dynamic event-triggered predictive control for networked control systems

Abstract

This paper investigates the output-based predictive control problem for networked control systems (NCSs) with delays and data loss using the dynamic event-triggered mechanism (DETM). And the output-based DETM is proposed to utilize the network resources more efficiently while ensuring the system performance. The combination of DETM and observer-based networked predictive control (NPC) approach is developed to actively compensate the network delays and data loss, which enables the closed-loop system to maintain the desired performance and stability. In addition, a sufficient condition is deduced to ensure the stability of the NPC system by adopting an augmented model approach. Finally, the validity of the design procedure is demonstrated by an example.
