    摘要:

    為了有效提高農(nóng)業(yè)灌溉用水的利用率,根據(jù)農(nóng)業(yè)灌溉的用水量,采用2級(jí)灌溉,先蓄水再灌溉的策略。在每次灌溉前,根據(jù)動(dòng)態(tài)時(shí)間彎曲-迭代學(xué)習(xí)控制(DTW-ILC)方法的思想,先計(jì)算出灌溉用水,將其存放在蓄水池中,再根據(jù)實(shí)際農(nóng)業(yè)灌溉用水量進(jìn)行灌溉,反復(fù)用計(jì)算出來(lái)的蓄水池儲(chǔ)水量逼近實(shí)際用水量,達(dá)到修正系統(tǒng)參考模型的作用,同時(shí)將下次灌溉的用水存儲(chǔ)在蓄水池中,可以很好地預(yù)防干旱帶來(lái)的無(wú)水灌溉的問(wèn)題。仿真結(jié)果表明經(jīng)過(guò)幾次蓄水灌溉的過(guò)程可以很好地跟蹤農(nóng)業(yè)灌溉的實(shí)際用水量,提前作好蓄水池的蓄水工作,需要灌溉時(shí)有適當(dāng)?shù)墓喔扔盟?,減少浪費(fèi),最終達(dá)到節(jié)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.
