基于线性化模型的LCL滤波并网逆变器PWM-SMC控制器设计

Nowadays, various sliding-mode control (SMC) methods have been successfully applied to the digitally controlled grid-connected inverter (GCI) with an LCL filter. However, how to design the pulsewidth modulation based SMC (PWM-SMC) controller needs to be further explored, especially upon the large variation of the parameters drift and the delay issue. In this article, the essence of two classic SMC...
