| 中文摘要 |
| 为了克服传统矩阵变换器电压传输比低的缺陷, 提出了新型Buck-Boost矩阵变换器, 采用双闭环控制策略进行控制. 介绍了该控制策略的基本原理与设计方法, 对比分析了该控制策略与滑模控制及离散滑模控制的各种特性, 并通过仿真对其控制效果进行了验证. 结果表明: 该控制策略不仅具有比滑模控制和离散滑模控制更加优良的动态性能, 而且还具有更强的谐波抑制能力, 其输出波形的谐波失真度更小, 稳态精度更高, 因而具有更好的应用价值. |
| 英文摘要 |
| Because of the low voltage transfer ratio in a conventional matrix converter and no improvement can be made by employing different control strategies, a new Buck-Boost matrix converter is proposed by employing a doubleloop control strategy. The fundamental principle of this control strategy and its design method are introduced. Various characteristics are then compared among this control strategy, the sliding mode control and the discrete sliding mode control. The validity of this control strategy is also tested by simulation. The results show that the double-loop control strategy makes the system in better dynamic performance and stronger harmonic suppression than the sliding mode control and the discrete sliding mode control, and achieves lower harmonic distortion and higher steady-state precision. These are the most valuable advantages of the proposed converter in engineering applications. |
