An emergency control scheme is proposed for pools upstream of a canal experiencing flow obstruction incidents. In order to achieve a prompt and efficient transition process, operation strategies are set out. It is suggested to switch from a constant downstream depth operation method to a constant volume operation method under qualified conditions. Based on a balanced pool operation equation and a transitional time estimation e...

A control system consisting of a decentralized feedback controller, a centralized feedforward controller and a decoupler is presented for the Middle Route Project for South‐to‐North Water Transfer in China. The feedback controller is a kind of level‐discharge cascade adaptive PI controller, which has the merit of diminishing unknown disturbances and reducing coupling effects of the control action on downstream canal pools. The...
