摘要

本文提出了一种用于中高压系统的五电平混合箝位逆变器的改进有限控制集模型预测控制(FCS-MPC)。所提出的控制策略有效地减少了计算负担，仅利用512个开关状态，这是传统FCS-MPC中使用的八分之一。成本函数中包含直流电压调节、逆变器电流纹波、浮电容电压平衡、开关频率最小化等控制目标。对不同操作的性能都进行了评估。在MATLAB/Simulink环境下验证了该FCS策略的性能。

An Improved FCS-MPC Algorithm for Three-Phase Five-Level Hybrid-Clamed Converter

in this paper, an improved finite control set-model predictive control (FCS-MPC) of five-level hybrid-clamped inverter used in middle and high voltage systems is presented. The proposed control strategies reduce computation burden effectively, utilizing only 512 switching states which is one eighth of that used in a conventional FCS-MPC. The control objectives of regulation of dc-link voltage, ripple of inverter current, floating capacitor voltages balancing, and switching frequency minimization are included in the cost function. The performance at different operations are all evaluated. The performance of the proposed FCS strategy is proved in MATLAB/Simulink environment.
