| Abstract: |
| Aimed at the shortcomings of a traditional fixed-gain compensator such as low synchronization precision and slow compensation speed, a novel type of synchronous compensator with fuzzy and pre-compensation functions is proposed. At the same time, by overcoming the limitation of only improving the synchronous compensation strategy in the past, a sliding mode controller with load torque feedback is designed to improve the synchronization performance by improving the tracking controller. Simulation results show that compared with the fixed-gain compensator, the novel synchronous compensator has a faster compensation speed and a higher synchronization precision. Moreover, the robustness and synchronization accuracy of the whole system are obviously improved owing to the designed sliding mode controller with load torque feedback. |
