Abstract：Energy consumption during the operation of coal mine belt conveyors is closely related to the feed rate and belt speed.Thus it is significant for energy-saving operation of the belt conveyors to real-time optimize the belt speed according to the feed rate.This paper studies the problems of energy consumption modeling and parameter identification for dual-motor driven coal mine belt conveyors.Firstly,taking into account the structure characteristics of dual-motor driven systems,a new energy model is established.Then,based on the measurements of motor current,speed and feed rate,a parameter identification method is derived by using flux linkage observer and recursive least square.Finally,the proposed method is illustrated by simulations.
