针对风力提水系统风、辅动力存在耦合使控制效果难以保证的问题,该文提出了一种基于逆模型解耦的变论域模糊控制方法。采用神经网络方法辨识风力提水系统的逆系统,并与被控对象进行串联,建立伪线性系统,实现风、辅动力解耦。同时采用模糊控制器对风、辅动力分别进行独立控制,对模糊控制器的论域进行改进,增强系统的环境适应能力。逆模型仿真试验中变量泵控制和柴油机控制量平均误差分别为6.3%和4.5%,实际运行中离心泵的转速平均误差控制在5%以内,说明该文方法能有效抑制风速变化的影响。研究结果对风力提水系统的推广具有重要的意义。

In recent years, with the development of new energy technology, a hybrid water system of wind power and conventional energy supplement was rapidly developed in China. However, wind resources are affected by seasonal and geographical patterns, water system, wind energy, and conventional energy cooperation. The two are mutual coupling, so the control effect is difficult to guarantee. Therefore studies of one kind of establishment of auxiliary control system based on dynamic decoupling in the wind, the stability, water effect, and promotion of wind water pumping technology to solve the power shor...
