摘　　要：针对光伏发电系统的非线性、强耦合、不确定特性,采用一种基于T-S模糊模型的光伏发电系统局部线性建模方法,并根据建立的局部线性模型,采用并行分布补偿(PDC)控制策略设计了光伏局部线性子系统的T-S模糊控制器增益。通过局部线性子系统的加权求和得到全局非线性系统的T-S模糊模型和模糊控制器增益。基于MATLAB/SIMULINK建立了系统动态仿真模型,仿真结果表明所设计的T-S模糊控制器用于光伏最大功率点跟踪具有可行性,同时保证了系统最大功率点跟踪具有足够的稳态精度与跟踪速度。Due to the nonlinear,strong coupling and uncertain characteristics of PV system,this paper establishes a local linear model for PV system based on T-S fuzzy model.According to the established local linear model,the T-S fuzzy controller gain of PV local linear subsystem is designed by using the parallel distributed compensation(PDC)control strategy.The T-S fuzzy model and fuzzy controller gain of the whole nonlinear system are obtained by the weighted sum of the local linear subsystem.The system dynamic simulation model based on MATLAB/SIMULINK is established.The simulation results show that the designed T-S fuzzy controller is feasible for PV maximum power point tracking.Its steady-state accuracy and tracking speed are enough to ensure the maximum power point tracking of the system.
