【Abstract】 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.更多还原
