中文摘要

本文提出了一种积分滑模控制(ISMC)策略,旨在优化升压衍生DC-DC-AC变换器的控制性能。ISMC通过结合标称控制与不连续滑模控制,有效抑制了单相系统中常见的2倍频纹波,增强了系统对参数不确定性的鲁棒性,并显著提升了变换器的动态响应速度。

English Abstract

In controller design, the classical control techniques have their distinct advantages and capabilities. The integral slidingmode control (ISMC) leverages the merits of such control techniques by allowing their merger with the sliding-mode control (SMC). ISMC is composed of two components, a nominal control designed using any methodology and a discontinuous-SMC, and thus the system can have specifi...
