| Abstract: | The necessities of the Ethernet application for industrial field were summarized in this paper. An Ethernet based on closed loop system model was introduced. An observer and an estimator were designed to release the effect caused by transport delay existing in the network control system. The introduction of the observer and the estimator keep the system stable and has a fine performance. A simulation was given to demonstrate the effectiveness of the design method. |
