论文摘要
本文分析了灵敏度调节控制策略，并将其应用于电力电子转换器。该术语用于改善闭环系统，例如具有级联的内环控制器和外部环控制器的电源转换器。使用单数扰动理论分析灵敏度项的影响。此外，对控制项的实施是针对实际系统的，其中输入数量通常不足以用于精确的灵敏度调节。给出了带有输出电容器电压调节的降压转换器和一个永久磁铁同步机（PMSM）的模拟结果，该计算机用作具有活性整流器的发电机。最后，给出了雄鹿转换器的实验结果，证明了实现闭环功率转换器的近似灵敏度条件项的优势和可行性。
A sensitivity conditioning control strategy is analyzed in this paper and it is applied to power electronic converters. The term is used to improve closed loop systems, such as power converters with cascaded inner and outer loop controllers. The impact of the sensitivity term is analyzed using singular perturbation theory. In addition, the implementation of the control term is addressed for practical systems, where the number of inputs is generally not sufficient for exact sensitivity conditioning. Simulation results are presented for a buck converter with output capacitor voltage regulation and a Permanent Magnet Synchronous Machine (PMSM), used as a generator with an active rectifier. Finally, experimental results are presented for the buck converter, demonstrating the advantages and feasibility in implementing the approximate sensitivity conditioning term for closed loop power converters.
