Abstract
En 中文
This paper addresses the exponential synchronization challenges in coupled network systems subjected to impulsive effects and bandwidth-constrained communication channels. We introduce a novel hybrid quantization framework that synergistically integrates logarithmic and dynamic quantization mechanisms to optimize synchronization performance under limited bandwidth conditions. The framework systematically accounts for the dual nature of impulsive effects- manifested as both control inputs and system disturbances- through carefully designed quantization parameters tailored to each scenario. Utilizing Lyapunov stability theory, we establish comprehensive synchronization criteria that characterize system behavior under various impulsive conditions. The theoretical developments are validated through two detailed numerical simulation studies, demonstrating the effectiveness and practical applicability of the proposed hybrid quantization approach.
