The paper extends the automatic tuning method proposed by the authors for the case of a single pool to the case of multiple-pool canal. The relay experiment is used to automatically compute the decouplers, and the controller is automatically switched on after the relay test, leading to a set of decentralized distant downstream PI controllers with decouplers. The method is evaluated in simulation and in reality on a large scale irrigation canal pool located in the South of France.
