Experimental Study on Decoupling Algorithm of Automatic Control Canal
Coupling effects among pools are the key reason to induce persistent water fluctuation and decrease response and recovery characteristic of automatic control canal. Combined with theoretical analysis and physical experiment method t revised Decoupler I is studied herein. The algorithm decouples in upstream direction by means of feedforward control and in downstream direction by appending a flow controller. The experiment is carried out in a 317m long, 0. 6m wide, 5-pool test canal in China IWHR. The canal is operated using constant downstream depth operation method and Proportional-Integral (PI) decentralized control scheme. Different decoupler coefficients ranging from 0 to 1. 0 are tested. Experimental results are proved to be consistent with simulation ones. Revised Decoupler I functions well both in upstream direction and downstream direction, on condition that proper decoupler coefficients are selected.
