| 摘 要： | 控制系统中任务的调度不仅影响系统的资源利用率,而且影响系统的控制性能。首先分析了周期性实时任务,并给出了任务模型。基于此,采用了EDF调度算法。根据系统的性能指标与任务的采样周期的关系,采用粒子群算法对系统性能进行优化。仿真结果表明,这种算法是有效的。

| Abstract: | Task scheduling for control system influences not only on the resource utilization of system,but also on the control performance of system.Firstly,real-time periodic task was investigated and task model was given.Based on this,EDF algorithm was adopted to schedule this kind of task.According to the relationship of the performance of control system and sampling periods,the performance was optimized based on PSO.Simulation results show that the algorithm presented in this paper is effective. |
