| 摘 要： | 网络控制系统NCS(Networked Control system)是基于网络的分布式控制系统，具有强实时性。结合控制网络的实时调度与系统控制性能，应用单调速率RM(Rate Monotonic)方法对一组周期性的网络控制传输任务进行调度，采用遗传算法实现NCS的调度优化，同时满足了网络传输的优化调度与控制系统传输误差最小化的要求，提高了网络控制系统的性能，最后给出了优化实例。

| Abstract: | The NCS (Network Control System) is a network-based distributed control system with strong real-time performance.In this paper,with the combination of the real-time scheduling and the system control performance,a rate monotonic method is used to implement the scheduling of a set of periodic tasks for NCSs and a genetic algorithm is applied as well to the realization of NCS scheduling optimization.The scheduling condition of network transmission is improved and the minimization of transmission errors of NCS is fulfilled simultaneously,thus the performance of the networked control system gets better.An example is shown at the end of the paper. |
