Abstract |
|
With growing technology, number of control system elements is increasing. So, it is not possible to place entire control system at a same place. Therefore, separate control elements connected by a communication link are required, it introduces delay. This delay is either constant or random in nature depending on communication link. This delay destabilizes the overall system and can be compensated using smith predictor. But smith predictor is only applicable to constant delay communication links. In this paper, communication disturbance observer (CDOB) and network disturbance (ND) have been introduced to compensate variable delay in communication link. |
