控制系統(tǒng)中實時任務分析

本文分析了控制系統(tǒng)任務的特點，給出了控制系統(tǒng)中各種實時任務模型。分析了
控制系統(tǒng)性能與任務參數(shù)之間的關系，給出了參數(shù)的設置方法。最后，研究了控制系統(tǒng)中實時任務之間存在關系，包括資源共享、執(zhí)行順序及一致性限制，給出了處理這些關系的方法。
關鍵詞：實時控制系統(tǒng)，任務模型，資源共享，一致性約束
Abstract: The characteristic of tasks in control systems is analyzed in this paper and the task
models are presented. The relationship between the performance of control system and parameters of tasks is investigated and the method for setting up them parameters is given. Finally, the relationship between tasks is studied. It is pointed that there exist resource sharing, execution order and consistency constraint among tasks. The methods for handling these relationships are given.
Keywords: Real-time Control system, task model, resource sharing, consistency constraint
