控制系统的标准设计基于周期性采样。每个时期都从输入中读取数据，计算控制定律，并将输出写入执行器。但是，采样瞬间的周期性是由实施易于实施产生的约束，并且在控制系统中并不是必需的。在本文中，我们提出了一个执行模型，该模型“在需要时”采样输入。该模型节省了大量的计算资源。我们使用固定优先级（FP）和最早的截止日期（EDF）展示了一组控制驱动的任务的计划分析。
The standard design of control systems is based on the periodic sampling. Every period the data is read from the input, the control law is computed, and the output is written to the actuators. However the periodicity of the sampling instants is a constraint that arises from the ease of implementation and it is not strictly necessary in the control system. In this paper we present an execution model that samples the input "when needed". This model saves a considerable amount of computational resources. We show the schedulability analysis for a set of control-driven tasks using both Fixed Priority (FP) and Earliest Deadline First (EDF).
