Study of a Control Algorithm with the Disturbance of Massive Discharge on an Open Channel

The diversion of large flows water in open channels, which exceed safe levels, into storage systems is the focus this paper. We focused upon middle route South-to-North Water Transfer Project and ancient canal gate 4 drainage pool. estimated quantity amount compensation offered. used improved PID algorithm to study 20 disturbance flow pipe heads. results show that can suppress fluctuation level a certain extent, but, for caused by flows, maximum front Shahei sluice control capable more than 0.3 m, much larger constraint line channel pool, where rate drop should not 0.15 m per hour. However, case disturbance, variation all gates area 0.1 meets severe project, effect good, protects operation safety
