用于四电平逆变器多级预测电流控制的增强型采样数据模型

The use of forward Euler-based sampled-data models in multistage predictive current control (MS-PCC) for multilevel inverters (MLIs) results in a poor prediction accuracy with the rise in sampling time. These models also lead to higher harmonic distortion and capacitor voltage ripple in MLIs. To address these problems, modified Euler-based models are proposed for an MS-PCC, and they are applied to...
