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.
