摘要
Abstract
The LCL motor inverter is modeled using the complex vector in the synchronous rotating reference frame(SRF),and the influence of the overall phase margin and coupling performance of the system under different control strategies is thoroughly investigated.The analysis reveals that the inverter has a coupling relationship between the dq axes,and the active damping feedback branch also intensifies the coupling phenomenon.To address these issues,a complex vector decoupling strategy is proposed.The decoupling components for the active damping feedback branch and the current loop system are sequentially designed.The decoupling elements are applied to both the feedback branch and the output current of the PI controller respectively,which not only effectively eliminate the dynamic coupling but also enhances the system's dynamic performance.Finally,the effectiveness of the control strategy is verified by comparing the simulation and experimental results with the traditional decoupling control.关键词
