基于模糊幂次趋近律的Vienna整流器直接功率控制研究

摘要/Abstract

摘要： 针对Vienna整流器的传统控制方法存在抗干扰能力差、中点电压波动等问题,提出了一种基于模糊幂次趋近律的直接功率控制策略。该策略以瞬时有功功率、无功功率、上下电容电压差的参考误差为状态量建立滑模面,并通过设计模糊规则形成了可自适应调节幂次项的趋近律。仿真和实验结果验证,该策略能够兼顾单位功率因数运行、输出电压稳定和中点电位平衡等控制目标,且相比双闭环PI控制策略具有更好的动态、稳态和鲁棒性能。

Abstract: In order to overcome the limitations of traditional control methods including bad robust performance and fluctuation of neutral point potential,a direct power control strategy based on a fuzzy power reaching law for three-phase Vienna rectifier was proposed.In the strategy, the sliding mode surface was established by using the reference error of instantaneous active power, reactive power and voltage difference between upper and lower capacitances, and the approach law with adaptive power term was formed by designing fuzzy rules. The simulation and experimental results show that the control strategy can take into account the control targets including unit power factor operation, output voltage stability and midpoint potential balance, and compared with the double closed-loop PI control strategy, it has better dynamic, steady-state and robust performance.

Key words: Vienna rectifiers, reaching law, direct power control(DPC), neutral-point potential, sliding mode control
