摘要
带式输送机运行过程中的能耗与原煤运量和带速关系密切,根据运量优化带速,对于输送机节能运行有重要意义.本文面向煤矿双电机驱动带式输送机节能运行,研究能耗建模和参数辨识方法.首先,根据双电机驱动模式,建立基于电机动态模型的输送机能耗模型;然后,根据电机电流、转速和运量的测量数据,建立基于磁链观测器和递推最小二乘的参数辨识方法;最后,通过仿真实验说明所提方法的有效性.
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.
