中文摘要：

有源电力滤波器（APF）是解决电力系统谐波治理的有效方法,由于电源电压存在畸变影响了APF的补偿参考电流的检测精度并影响补偿的效果.本文采用T–S模糊控制的方法对三相三线APF进行建模,将电源电压的畸变成分作为理想情况的干扰,在保性能的前提下给定性能指标,实现T–S模糊H∞控制性能.在满足稳定性的要求条件下,设计的T–S模糊H∞状态反馈控制器使APF在电源电压畸变的情况下,将电源电流补偿为正弦特性,满足了APF谐波综合补偿的控制要求.仿真结果验证了所建T–S模糊模型的有效性,展示出所设计的H∞控制器的有效性能.补偿电流可以准确的检测,在电源电压非正弦条件下可以进行有效的控制.

英文摘要：

The active power filter （APF） is an effective tool for harmonics abatement and power quality improvement, but the distortion of the power voltage deteriorates the accuracy in current detection and reduces the efficiency of compensation. To tackle this problem, we employ Takagi-Sugeno （T-S） fuzzy control method to build the model of the three-phase-three- wire APF in which the power voltage distortion is considered the disturbance to the idea model, and realize the T-S fuzzy H-infinity control with a given performance index. Satisfying the required stability, the designed T-S fuzzy H-infinity feedback controller makes the APF restoring the distorted power voltage to a voltage with sinusoidal characteristics, meeting the requirements of comprehensive compensation. Computer simulations show the validity of the T-S fuzzy control model and the efficacy of the H-infinity feedback controller. The reference compensation current can be detected accurately, and the controller is able to carry out the operation under the circumstance of non-sinusoidal power voltage.
