摘要: 本文提出了控制人民胜利渠地下水位埋深的数学模型,并按灰色系统的多目标局势决策, 从"适灌"、"防次"、"经济"三目标出发,确定了最优灌溉决策.实践证明,这种决策收益大、效 果好,年内水位系统状态变化良好,埋深较大,是一种优化的地下水位埋深的控制系统.Abstract: The mathematical model of the depth of burying of underground water of the People's Victory Channel, and its automatic control systems are proposed in this paper. Optimal irrigation strategy is determined according to multiple objective grey decision-making from the three goals, i.e. "proper irrigation time", "prevention of alkalification" and "economy". Practice proves that gains and effects of this strategy are saris. factory. State of underground water level within a year is excellent, and burying level is deeper. It is an optimal control system for the depth of burying of underground water.
