Real-time systems, especially software control systems, are developed to meet the requirements of real-time automation systems. One such crucial requirement is reducing the delay and jitter of periodic tasks in such systems. In this paper, we present a new method for reducing delays and jitters of periodic tasks, which are enforced by the operating system, control tasks, kernel mechanisms, etc. Our algorithm is evaluated and compared with other scheduling algorithms in terms of jitter. The effectiveness of our algorithm is confirmed by the experimental results.
