| 针对大功率晶闸管电压调节器在移相调压过程中产生的谐波电流，提出适合于就地补偿的新型模糊反馈电流检测有源电力滤波器方案，有效解决补偿电流的检测以及有源滤波器的非线性控制问题。对移相调压产生的谐波及三相有源电力滤波器进行电路模型分析，采用Takagi-Sugeno模糊反馈控制方法直接检测电网电流，基于并行分布补偿的方法设计了模糊反馈控制器，在稳定性的条件下求解线性矩阵不等式，得到模糊控制器补偿控制策略的状态反馈增益。仿真及实验结果验证了有源电力滤波器补偿电流检测的准确性及模糊反馈控制的有效性。 |

| Abstract: |
| An APF（Active Power Filter） with fuzzy feedback currents examination is proposed to locally compensate the harmonic currents caused by powerful thyristor PSVR（Phase-Shifted Voltage Regulator）. Based on the harmonics analysis of PSVR and the math model analysis of three-phase APF，T-S（Takagi-Sugeno） fuzzy feedback control is adopted to directly examine the grid current，and based on the parallel distributed compensation，the fuzzy feedback controller is designed. The stable feedback gains are achieved by solving the linear matrix inequation under the stability conditions. Simulations and experiments indicate the correctness of compensating current examination and the effectiveness of fuzzy feedback control. |
