| Popis: | The closed-loop delay is one of the most important factors affecting the control performance of a wide-area control system (WACS), due to the network transmission of feedback and control signals. A prediction based hierarchical delay compensation (PHDC) method is proposed in this letter at the data processing level to deal with delays. For the control strategy on the top-level, all feedback and control information are real-time and transparent without consideration of delay. The PHDC method compensates the random and distributed delay effectively and reduces the impact of delays on the control performance. |
