Filtering of jitter based on inverse related filters and error corrector in network control systems

Network control systems have been attracting attention to manage sophisticated task at a remote place where people cannot enter. However, jitter which is a fluctuation in time delay for an information to be transmitted, is a serious problem in network control systems because it deteriorates the performance of the system. Therefore, designing control system considering jitter is extremely important. Thus, this paper proposes a novel method to reduce the effect of jitter to the system under time delayed conditions. This is done by utilizing two filters that have inverse relationships and an error corrector when information is transmitted via network. The validity of the proposed system is confirmed experimentally by implementing the proposed filter to a one way information transmission and a network control system. Also, the experimental results of the proposed method is compared with conventional methods to show the effectiveness of the proposed method.
