Co-Design of Quantization and Event-Driven Control for Networked Control Systems

This paper considers the co-design technique of quantization and event-driven control for reducing the negative influences of network on the system performance of networked control systems (NCSs). Event-driven strategy aims at reducing the frequency of transmission, while signal quantization reduces the amounts of data for each transmission. By combining these two techniques, this paper establishes the quantized event-driven control approaches for both the fixed and relative event threshold cases. The system stability and the existence of the minimum interevent interval (MIEI) are analyzed. Finally, the validity of the proposed approaches is illustrated by the numerical simulations.

This paper discusses the co-design technique of quantization and event-driven control to reduce the negative impacts of the network on the system performance of NCSs. By combining event-driven strategy and signal quantization, quantized event-driven control approaches are established for both fixed and relative event threshold cases, with analysis done on system stability and the existence of minimum interevent intervals (MIEI). The validity of the proposed approaches is demonstrated through numerical simulations.
