Abstract

A fuzzy logic controller for an active power line conditioner (APLC) is described. Frequency-domain analysis is used to determine the desired compensation current, and a rule-based piecewise linear fuzzy proportional-integral controller (FPIC) provides the appropriate switching pattern of the APLC to generate the actual compensation current. Both MATLAB simulations and experimental measurements on a low-power, digital signal processor (DSP) based, hardware prototype are described. The simulations and measurements agree very well and show that the APLC/FPIC system can significantly improve both total harmonic distortion and power factor during both steady-state and transient operating conditions.

带有模糊逻辑开关控制器的有源电力线调节器的实验验证
介绍了一种用于有源电力线调节器的模糊控制器。通过频域分析确定所需的补偿电流,基于规则的分段线性模糊比例积分控制器(FPIC)为APLC提供适当的开关方式以产生实际补偿电流。介绍了基于低功耗数字信号处理器(DSP)的硬件样机的MATLAB仿真和实验测量。仿真结果与实测结果吻合良好,表明APLC/FPIC系统在稳态和暂态工况下均能显著改善总谐波畸变和功率因数。
