摘要

针对与光伏(PV)系统相连接的单相电压源逆变器(VSI)，研究了一种模糊滑模控制(Fuzzy-SMC)方案。该控制器能够鲁棒平滑地控制系统的实功率和无功功率，并能处理系统参数的不确定性和外部干扰。根据李雅普诺夫稳定性判据证明了所得到的控制律的稳定性。通过Dspace 1104实时实现板的实验验证了所采用策略的有效性。在不同负载水平下的实验结果表明，与SMC相比，模糊SMC具有更强的暂态性能和更低的输出电流和电压的总谐波失真(THD)。

Experimental Evaluation of Fuzzy-Sliding Mode Control Applied to A Single Phase VSI For Photovoltaic Application

This study investigates a Fuzzy-Sliding mode control (Fuzzy-SMC) scheme for a single-phase Voltage Source Inverter (VSI) interfacing a photovoltaic (PV) system. The suggested controller is developed to control the real and reactive power in a robust and smooth way and deal with the system parameter uncertainties and external disturbances. The stability of the obtained control laws is proved according to Lyapunov stability criterion. The effectiveness of the adopted strategy is validated through an experimental verification using a Dspace 1104 real-time implementation board. The experimental results, under different load levels, demonstrate that the Fuzzy-SMC provides enhanced transient performance and lower Total Harmonic Distortion (THD) of the output current and voltage in comparison with SMC.
