摘　　要：针对网络控制系统的闭环性能受网络调度QoS与控制性能QoP两个方面决定,采用基于QoS管理的兼顾网络调度QoS与控制性能QoP两方面的协同设计。从分析QoS性能指标入手,阐述了QoS功能以及QoS的管理过程,并由QoS求出网络时延,并设计控制器,如NCS闭环的QoP不能满足,需改变QoS使NCS的闭环性能符合要求。最后,以实例仿真对比说明对总线网络进行QoS管理的协同设计,可以在很大程度上提高网络传输效率,减少传输时延及其抖动程度。Due to the closed loop performance of networked control system decided by the quality of service and the quality of performance, the co-design strategy based on QoS management that considers both QoS and QoP is put forward. Firstly, the performance parameters, functions and the management process of QoS are discussed. Secondly, the co-desgin process is expounded： time delay of NCS is obtained by QoS, controller is designed and QoP is solved, and then QoP is consilient by changing QoS. Finally, the co-design strategy based on QoS management can improve the transferring efficiency, reduce the delay and delay jitter with examples.
