Processing method for water division disturbance of constant flow zone in channel control

The invention relates to a processing method for water division disturbance of a constant flow zone in channel control. The method comprises the following steps of: firstly, calculating feedforward control time corresponding to a water division channel of the constant flow zone according to a downstream water quantity constant thought; then calculating feedforward time under different working conditions to obtain a fitting formula of feedforward control time of the water diversion channel; and finally, according to the obtained fitting formula, proposing a processing thought of converting thewater division disturbance of the constant flow zone into the water division disturbance of a water return zone, and realizing the transfer from the water division disturbance of the constant flow zone to the water division disturbance of the water return zone. According to the invention, the feedforward control time of the channel section is utilized to transfer the control problem of the dividedwater flow change of the
