Multi-channel flow distribution method and multi-channel flow distribution system

Abstract

The invention discloses a multi-channel flow distribution method and a multi-channel flow distribution system. The multi-channel flow distribution method comprises the following steps: firstly, setting target flow of a source generating device according to the sum of flows of all the branches; secondly, driving a regulating valve of the source generating device by a computer measurement and control system, so that outlet flow of the source generating device reaches a set target value; and thirdly, sequentially driving the regulating valve of each branch by the computer measurement and control system, so that each branch reaches respective preset flow, wherein in the steps 1, 2 and 3, the flow is regulated by adopting a DRNN neural network and a PID algorithm. The multi-channel flow distribution method disclosed by the invention can realize and complete a method for distributing flows to multiple branches from one source, real-time adjustment is carried out by virtue of the computer measurement and control system via a PID control algorithm and the DRNN neural network, and the whole flow distribution forms flow control in a negative feedback form, so that the flow of each branch is more accurately controlled.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a multi-channel flow distribution method and a multi-channel flow distribution system. Background technique [0002] Flow distribution is widely used in the engineering field, generally divided into liquid flow control and gas flow control. However, the current applications are completed by some special equipment, basically a set of equipment is only for one working condition, the utilization rate of the equipment is low, and the cost is high. [0003] Moreover, the existing flow distribution work cannot adjust the flow in real time, especially when accurate flow is required, it is impossible to determine whether the real-time flow meets the demand. [0004] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention [0005] The purpose of the present inv...
