摘要 在搭建的虚拟平台上对多任务的网络控制系统调度和嵌入LQG控制算法进行了仿真,探索了网络控制系统中调度与控制协同设计方法,讨论系统采样周期对网络控制系统的影响,以优化控制系统的性能为目标,以网络的可调度性为条件,结合系统控制和调度算法,对网络控制系统进行静态性能指标估计和动态调度仿真相结合,结果表明该方法既满足了控制系统的性能,又优化了网络的调度,提高了网络的资源率。 Based on existent results on control network performance and scheduling in protocol layer, the multi-task networked control systems for scheduling simulation in virtual platform is considered. In addition, technologies for integration of control and scheduling design are explored. The influence of sampling period to NCS is discussed. Based on the proposed quadratic cost functon and network scheduling, an optimization model and sampling period selection algorithm are proposed. An example shows that the algorithm satisfies performance requirement for NCS, optimizes the network scheduling, and improves the network efficiency.
