The simulation research on the isolated intelligent system of wind supplied water pumping machine

着重研究了以无刷直流电动机(Brushless DC Motor,BLDCM)控制器为核心的小型风力提水机系统的MATLAB/Simulink仿真模型。阐述了无刷直流电动机的工作原理,对小型风力提水机控制系统进行了数学建模和仿真分析,并重点对BLDCM转速闭环系统的运行情况进行了仿真,验证了该系统可实现闭环调速,能根据风力大小自动提高出水量。

This paper studies the MATLAB / Simulink simulation mode of the system of water pumping machine supplied by wind,especially its core,the Brushless DC Motor（ BLDCM） controller. A mathematical model is founded and simulation is done by using MATLAB after explaining the working principle of BLDCM system. The closed-loop operation situation of the whole system has been observed through MATLAB simulation. Thus,it can realize closed-loop speed control and pumping water automatically according to the strength of wind.
