摘要: 基于6/4极开关磁阻电机(SRM),提出了一种具有模糊控制的最大功率点跟踪(MPPT)和SRM转速控制的光伏水泵系统及相应模糊控制方法。在系统整体控制策略的基础上,分析了光伏阵列数学模型,并建立了SRM机电模型,在Matlab/Simulink环境下搭建了光伏水泵系统整体仿真模型。仿真与实验结果表明,模糊控制MPPT算法较好地实现了光伏阵列输出功率的稳定。此外,通过对SRM转速进行有效控制,各相磁链曲线与相电流曲线表明SRM工作稳定,验证了所提出光伏水泵系统与模糊控制器的可行性。

Abstract: A photovoltaic(PV) pumping system and corresponding control method with fuzzy controlled maximum power point tracing (MPPT) and rotor speed control of 6/4 switched reluctance motor(SRM) is proposed. Based on control strategy of whole system, mathematic model of PV array is analyzed, and mechatronic model of SRM is built. Then simulation model of PV pumping system is built in the MATLAB/Simulink. Simulation and experiment results reveal that proposed algorithm can realize stable tracing of PV array maximum power. Curves of flux linkage and current of each phase show stable SRM operation, which verify the feasibility of proposed PV pumping system and fuzzy controller.

Key words: PV pumping system, switched reluctance motor, PV array, simulation model
