Abstract
The present invention provides a distribution pressure controlling apparatus comprising section for supplying water in a distribution reservoir to a distributing pipe network, section for detecting an outlet pressure of water, section for detecting an outlet flow of water, section for detecting a distribution pressure of the distributing pipe network, a fuzzy table for storing a relationship between a deviation between a distribution pressure set by a user and the distribution pressure, the outlet flow, and an outlet pressure target value correction amount for correcting an outlet pressure of water, outputting section for obtaining the outlet pressure target value correction amount from the fuzzy table, based on the deviation between the distribution pressure set by the user and the distribution pressure, and the outlet flow, for correcting an outlet pressure target value with use of the outlet pressure target value correction amount, and for outputting the outlet pressure target value thus corrected; and section for controlling distributing section to be equalized to the distribution pressure set by the user, based on the outlet pressure target value and the outlet pressure.
