摘要:AbstractThe quantization of signals is a fundamental process in the operation of networked control systems. Some important quantization related problems include the system performance degradation, the channel data rate constraint, and the network traffic congestion. This paper develops a class of event-triggered dynamic quantizer that (i) minimizes the system performance degradation, (ii) satisfies the channel data rate constraint, and (iii) reduces the system network utilization rate. First, the quantizer design problem is formulated. Second, the design problem is solved by the differential evolution metaheuristic algorithm. Finally, with numerical examples the effectiveness of the event-triggered quantizer and its design method are verified.
