| Abstract: | A compensator is designed in a hydraulic telecontrol system based on Internet in order to improve the system performance affected by internet induced time delays in both forward loop and feedback loop. Forecast arithmetic such as the reason rule table method and the average value method are made use of in order to keep the system have a fine performance when the change of time delay is uncertain. The simulation shows that compensators and forecast arithmetic are effective both to keep the system stable and to limit the system overshoot and shorten the system's transient behavior. |
