Reducing control latency and jitter in real-time control

Tian, Yu-Chu, Han, Qing-Long, Tade, Moses O., & Levy, David (2006) Reducing control latency and jitter in real-time control. Asian Journal of Control, 8(1), pp. 72-75.


This paper analyses control computation latency and jitter, which have been largely ignored in the control community for real-time (RT) control. The focus is on RT control systems with multiple control tasks running on a uniprocessor. Three strategies are proposed to reduce control latency and/or jitter: introduction of offsets into control task scheduling, decomposition of control tasks; and increasing the priority levels of output subtasks. Examples are given to demonstrate the effectiveness of the proposed methods.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
