Optimal Parameters for Multi-pump Control System of Water Supply Based on Blind Source Separation

Abstract

In this work, finding the optimal parameters for multi-pump control system of water supply is regarded as a difficult problem in blind source separation (BSS). A motor acceleration or deceleration curve of water supply can be assumed a weighted sum by feature control parameters, such as pipe line pressure, water flux,and sleeping interval, etc. . With the help of restruction of separation model, a group of optimal parameters are found and the solution to to the optimal control parameters for multi-pump control system of water supply. The test results showed that maximal error(or separating precision) is 0.86% for two mainly feature parameters under a SNR of 9/231 and an excellent agreement between the numerical simulation and the actual test parameters is found.
