| 英文摘要 |
| A novel model of inner-feed chopper
cascade variable speed drive system using the state-space averaging
method is proposed in this paper. The dual closed loop control
strategy is then presented based on the model. The control circuits
for realizing the control strategy are also investigated. Finally, a
drive test is carried out, and the experiment results indicate the
feasibility of the model and control strategy. Based on the control
strategy, several devices with remarkable energy-saving effect are
running well in the industry field. They exhibit excellent
performance such as reliable DC-current protection ability, good
dynamic response and static precision. |
