| 摘 要： | 为了有效提高农业灌溉用水的利用率，根据农业灌溉的用水量，采用2级灌溉，先蓄水再灌溉的策略。在每次灌溉前，根据动态时间弯曲-迭代学习控制（DTW-ILC）方法的思想，先计算出灌溉用水，将其存放在蓄水池中，再根据实际农业灌溉用水量进行灌溉，反复用计算出来的蓄水池储水量逼近实际用水量，达到修正系统参考模型的作用，同时将下次灌溉的用水存储在蓄水池中，可以很好地预防干旱带来的无水灌溉的问题。仿真结果表明经过几次蓄水灌溉的过程可以很好地跟踪农业灌溉的实际用水量，提前作好蓄水池的蓄水工作，需要灌溉时有适当的灌溉用水，减少浪费，最终达到节水目的。

| Abstract: | In order to improve the utilization rate of agricultural irrigation water, according to the agricultural irrigation water use, two-steps irrigation was used. The strategy of first stockpile water and then irrigation was applied. Before irrigation every time, in accordance with the DTW-ILC algorithm, the irrigation water was calculated and then stored in the irrigation tank. The calculated irrigation water stored in pool was modified repeatedly close to the actual water consumption in agricultural irrigation. At the same time, the next irrigation water stored in the reservoir could be useful for preventing anhydrous irrigation. The simulation results showed that the actual water use in agriculture irrigation could be tracked well after several times of irrigation process. |
