Abstract: As a kind of special real-time system，network motion control systems’ performance is closely related to the scheduling of the resource（processor，network）.It is necessary to use real-time scheduling theory in NMCS.Based on the status quo of research on the classical uniprocessor real-time scheduling algorithm（RM and EDF） and network scheduling，similarities and differences of network scheduling and CPU scheduling，network scheduling method and application technology are studied.Finally，the application of RM and EDF scheduling algorithm in NMCS，scheduling optimization and the application problem are simulated.

摘要： 网络化运动控制系统作为一类特殊的实时系统，其系统的性能与资源（处理器、网络）的调度密切相关，将实时调度理论应用于网络化运动控制系统非常必要。在对用于单处理器的经典实时调度算法（RM和EDF）以及网络调度的研究现状进行综述的基础上，对网络调度和任务调度的异同点及网络调度的实现方法和应用技术进行了研究。最后，对RM和EDF两类调度算法在网络化运动控制系统中的应用及调度优化问题进行了仿真研究。
