A set of linear dynamic equations were obtained for a canal with multiple pools. The principles of optimal control and estimation theory were then applied to derive a decentralized controller and an observer for constant-volume control of irrigation canal pools in the presence of external disturbances acting on the system. using the linearized Saint-Venant equations and an example problem with 5 pools, the performance of the control algorithm in maintaining a constant-volume in the canal pools was found to be excellent.born digitalproceedings (reports)engCopyright and other restrictions may apply.
