基于Sigmoid函数的级联H桥多电平逆变器反馈线性化随机选择控制

To improve the steady-state and dynamic performance of cascaded H-bridge multilevel inverters (CHBMIs) and achieve power balance, this article proposes a control method based on the sigmoid function that combines feedback linearization with a random selection strategy. First, a continuous-smooth sigmoid function model that can uniformly describe all switching-state combinations is established. Sub...
