Abstract
An operating simulation mode for multireach serial canal system under gate regulating is established. The discharge feedforward plus water lever feedback PID controller is adopted. The performance indicators are introduced to evaluate the effects of canal operation control. Influence on dynamic response process and dynamic performance as well as the control actions of canal system is studied according to the variation of gate deadband. The results show: (1) when the gate deadband becomes larger, the control effect of canal system over water level becomes worse, and so does the stable process of gate discharge, yet the stable process of gate opening becomes better, while the upstream gate regulation of each canal pool is less at the time when canal stabilizes. (2) The closer to downstream end of canal, the lager steady-state error of this canal pool is, and the lager influence of gate deadband on the steady-state error as well as response time of this pool is. (3) the optimal value of gate deadband is 0.06m.
