Timing Studies of Real-Time Linux for Control

Abstract
Linux is being used increasingly for real-time control of industrial equipment. Versions of Linux adapted to support deterministic task execution are freely available. The resolution of task timing is much higher than for typical user-level processes, on the order of tens of microseconds. At this level, timing jitter due to hardward effects is visible. This paper describes Linux and real-time Linux, its application for industrial control, and shows the results of some timing studies. Various timing techniques are presented and their advantages and disadvantages are discussed. A method for improving timing is presented.Proceedings Title
