摘　　要：本文研究了随机环境下灌区调度问题,建立了一个水库和田间配水整合随机调度模型。文中引入土壤水库的概念,把灌区调度的问题转化成水库群调度的问题,采用线性二次高斯控制(LinearQuadraticGaussioncontrol,LQG)对模型进行求解,解决了此类研究中的求解技术难题,从而克服了前人模型中仿真性能不好的问题。此外,本文还对水库群调度中的LQG方法进行了改进。实例计算表明,本文建立的模型能取得良好的效益,LQG算法稳定、计算速度快。An integrated operation model for reservoir and canal irrigation system is developed for dispatch of irrigation area under the conditions of stochastic environment. The concept of soil reservoir is introduced into the model so that the dispatch of irrigation system can be regarded as the operation of multi - reservoir. The improved Linear Quadratic Guassian (LQG) Control method is applied to solve the model. By using this method the state variables should not be discrete and the problem of curse of dimensionality can be avoided. Example shows that the application of the proposed method result in good economic benefit, the algorithm of LQG control is stable and computation speed is high.
