Analysis of Overrun Strategies in Periodic Control Tasks

Cervin, Anton LU (2005) In Proceedings of the 16th IFAC World Congress
Abstract
The paper considers period overruns in control tasks with variationsin execution time (or response time). A simple model is used, wherethe input and output operations are assumed to be time-triggered,and the execution-time distribution of the task is assumed to beknown. Three overrun strategies, called Abort, Skip, andQueue, are modeled as discrete-time jump linear systems and areanalyzed with regard to control performance. The analysis isexemplified on an integrator process. It is argued that the Skipstrategy has good performance, is easy to analyze, and is simple toimplement in real-time operating systems. Some extensions to moredynamic models are also given.
