The complex vector decoupling control (CVDC) can achieve complete decoupling when the proportional coefficient (k(p)) and the integral coefficient (k(i)) of the current loops meet a certain proportion. But in most occasions, the k(p) and k(i) are out of that proportion, leading to incomplete decoupling. Thus, an improved complex vector decoupling control (ICVDC) is proposed. Based on the traditional CVDC, the current compensation is introduced to improve decoupling performance. The simulation results demonstrate the effectiveness of this method. Furthermore, the system shows good dynamic response performance and strong robustness.

Abstract
The complex vector decoupling control (CVDC) can achieve complete decoupling when the proportional coefficient (k(p)) and the integral coefficient (k(i)) of the current loops meet a certain proportion. But in most occasions, the k(p) and k(i) are out of that proportion, leading to incomplete decoupling. Thus, an improved complex vector decoupling control (ICVDC) is proposed. Based on the traditional CVDC, the current compensation is introduced to improve decoupling performance. The simulation results demonstrate the effectiveness of this method. Furthermore, the system shows good dynamic response performance and strong robustness.File in questo prodotto:
