摘　　要：通过对渠道运行动态水流的分析 ,提出平衡条件的计算方法 ,对渠道过渡过程的控制方程进行离散化、线性化 ,建立起渠道运行的状态空间方程 .并运用线性控制理论对渠道运行控制系统特性进行分析 ,确定渠道运行控制所需要的最少观测变量和观测位置 ,为用现代控制理论研究渠道运行自动控制提供一种理论和方法上的探讨依据 .By analyzing dynamic water of canal operation, a method for computing equilibrium condition of canal operation is proposed. Making the discretization and linearization of control equation of canal transition process, the state_space equation which describes the moving of water during the canal operation control is established. Linear control theory is applied to analyze the special property of canal operation control system, establishing the least observation variable and observation position during canal operation control. The results can provide reference and discussion for the research of canal operation automatic control by means of modern control theory.
