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.
