摘　　要：长距离带式输送机系统本身非常复杂,建立的动力学模型阶数较高,控制器的设计较为困难,本文利用平衡截断降阶法将高阶带式输送机系统模型化简为低阶的系统模型,在H2范数下对高阶与低阶系统的传递函数之间的误差进行评价,并从频域对其进行对比分析。The long distance belt conveyor system is very complicated itself,which results in high order dynamic model and difficult design of the controller.The paper introduces the balanced truncation method which simplifies the high order system model of the belt conveyor to the low order one,with evaluation for error of transfer functions between high order system and low order system under the H2norm,as well as comparison and analysis of it from the frequency domain.
