摘　　要：本文用现代控制理论研究渠道自动控制的设计理论和方法。从明渠控制方程出发,通过数学处理将描述渠道过渡过程的水力学方程转化为描述控制作用的动态方程,从而建立起渠道水流状态变化与闸门开度变化之间的关系。研究了渠道运行过程中的限制条件、性能指标和渠道运行全维状态反馈控制器的设计方法。提出了在有限水位测量和测量误差存在的情况下,完整的灌溉渠道测量—控制的设计方法。The modern control theory is applied to develop the design principle and method for automatic control of irrigation canal.The hydraulic equation describing the transient flow in canal is transformed into a dynamic equation expressing the control procedure. On this basis, the relationship between variation of flow state and gate opening is established.The limitations and performance indexes of operation are studied and the design method for all-dimension feedback controller is developed. A complete design method for operation control and measuring system is proposed.
