摘要 结合具有多控制回路的网络控制系统框架结构,设计了反馈调度器以实现调度策略.根据控制性能最优化要求,分析了系统的可调度性.通过实时调整各控制回路的采样周期,采用优先级分配方法,在线优化多控制回路的网络控制系统性能.通过对3个控制回路组成的网络控制系统进行仿真实验,验证了可调度分析和调度策略的有效性. In terms of the architecture of networked control systems with multi-control loops, a feedback scheduler is designed to implement the scheduling strategy. According to the requirement of control performance optimization, the system schedulability is analyzed. Control performances of networked control systems with multi-control loops can be optimized owline by adjusting sampling periods of loops and using the priority assignments. The schedulable analysis and scheduling strategy are validated by the simulation of networked control systems with three control loops.
