Various network‐based control systems using an Internet protocol (IP) network have recently gained attention. Time delays, jitters and packet losses occuring in the network, however, cause the performance degradation of the system. This paper presents a method to decrease the negative influences of the packet losses. The method to repair lost packets is that a sender sends a receiver a packet containing data sampled at a current period in the addition to the several previous periods. Speed control experiments of a commercial small DC motor are done using the method, the jitter buffer and a proportional and integral (PI) controller with a Smith compensator for confirming the effectiveness. Consequently, the present method has been found to be effective. Copyright © 2007 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
