Energy constrains are always significant to be considered in control of multiagent systems. Besides, nonlinear phenomena are often involved into such systems. In this paper, we discuss the impulsive consensus problem of nonlinear multiagent systems via impulsive protocol with limited bandwidth communication based on encoding-decoding. The scheme based on encoding-decoding with impulsive protocol is introduced to multiagent systems in general directed networks topology of which the graph is strongly connected. The impulsive protocols and limited bandwidth communication enhance the performance on energy saving and the involvement of nonlinear dynamics could suit more real-world cases. The design of encoders and decoders is presented, which is the key to achieve the goal that the information exchanged is subject to limited bandwidth communication. The conditions to guarantee the impulsive consensus and the conditions to avoid quantizer saturation are obtained. Moreover, the convergence rate of such multiagent systems are also characterized by the analysis of the exponential consensus. The numerical simulations are presented to support the theoretical results.
能量约束在多智能体系统的控制中始终是需要考虑的重要因素。此外,此类系统通常涉及非线性现象。本文基于编解码方法,通过具有有限带宽通信的脉冲协议,研究了非线性多智能体系统的脉冲一致性问题。该方案将基于编解码的脉冲协议引入到具有强连通图的一般有向网络拓扑结构的多智能体系统中。脉冲协议和有限带宽通信提高了节能性能,而非线性动力学的参与则更适合真实世界的情况。本文提出了编码器和解码器的设计,这是实现信息交换受限于有限带宽通信这一目标的关键。文中得到了保证脉冲一致性和避免量化器饱和的条件。此外,还通过指数一致性分析来描述此类多智能体系统的收敛速度。通过数值模拟验证了理论结果。
