| 摘 要： | 针对管道流量泄漏和管网突发性的爆管，以管道流量泄漏为应用对象，将模糊调度设计应用于管道流量泄漏监测中，研究具有模糊截止期的多控制任务的实时调度问题，提出奉献度概念和最大奉献优先（LDF）的调度策略。为了减小因任务间频繁切换造成的系统开销，提出基于抢占阈值的最大奉献优先（TLDF）调度策略。最后通过仿真比较LDF和TLDF两种调度策略，实现具有模糊截止期的控制任务调度，能够减少并均衡控制性能的损失，同时提高系统计算资源的使用率。

| Abstract: | Flow against pipeline leakage and the pipe network sudden burst pipe to pipeline leakage flow for the application ob- jects,fuzzy scheduling design flow used in pipeline leak monitoring.In order to improve the control performance of systems and use the limited computing resource reasonably,it is necessary to consider the collaborative design problem between control and real-time scheduling in computer controlled systems synthetically.In this paper,the real-time scheduling problem of multiple control tasks w... |
