可协调网络负载及冗余的调度器设计

Coordinated Network Load and Redundant Scheduler Design

笔者针对具有网络冗余结构的网络控制系统,在确保系统安全可靠的条件下,以提高系统的可用性为目标,设计了一个可协调通信负载并支持网络冗余的网络调度器。该调度器综合考虑了网络控制系统的服务质量和网络控制回路的控制性能,共同构成网络资源调度的目标函数,采用模糊系统建立网络资源调度策略,通过在线计算及实时调度,动态决策网络控制回路的通信信道,提高网络控制系统的实时性和可用性,并可完成冗余网络在故障条件下的快速切换,确保网络控制系统的可靠性。

Aiming at the networked control system with redundant network structure, aiming at ensuring the safety and reliability of the system, aiming at improving the usability of the system, a network scheduler that can coordinate the communication load and support the network redundancy is designed. The scheduler considers the control performance and quality of service and network control loop network control system, constitute the objective function of cyber source scheduling, established by the cyber source scheduling strategy of fuzzy system, through online calculation and real-time scheduling, communication channel dynamic decision network control loop, improve the real-time and availability of network control system fast switching, and can finish the redundant network in fault conditions, to ensure the reliability of the network control system.
