本文提出了对经典模型预测控制 (MPC) 算法的修改及其在有源电力滤波器中的应用。所提出的控制能够保留有限控制集 MPC 的所有优点，同时改善生成的波形谐波频谱。事实上，MPC 中固有地包含了一种基于不同输出向量的成本函数比的调制算法。介绍了基于成本函数的调制器，并证明了其在降低电流纹波方面的有效性。所提出的解决方案提供了一种有效且简单的单环控制器，尽管有调制输出，但仍保持出色的动态性能，并且与电网自同步。这种有前途的方法适用于并联有源滤波器的控制，通过无功功率补偿方法减少谐波含量。报告和评论了通过实验测试获得的重要结果，表明 MPC 是有源滤波系统的可行控制解决方案。
This paper presents a modification to the classical Model Predictive Control (MPC) algorithm and its application to active power filters. The proposed control is able to retain all the advantages of a finite control set MPC while improving the generated waveforms harmonic spectrum. In fact, a modulation algorithm, based on the cost function ratio for different output vectors, is inherently included in the MPC. The cost function-based modulator is introduced and its effectiveness on reducing the current ripple is demonstrated. The presented solution provides an effective and straightforward single loop controller, maintaining an excellent dynamic performance despite the modulated output and it is self-synchronizing with the grid. This promising method is applied to the control of a shunt active filter for harmonic content reduction through a reactive power compensation methodology. Significant results obtained by experimental testing are reported and commented, showing that MPC is a viable control solution for active filtering systems.
