摘　　要：针对带式输送机拉紧系统非线性、大惯性、滞后和时变的问题,建立了拉紧装置数学模型,并提出在其中串联一个校正环节,以消除系统振荡;提出将动态矩阵控制和PID控制相结合,充分利用动态矩阵对惯性、延迟适应能力强的特点和PID控制抗干扰性强的优点,建立带式输送机拉紧装置张力控制系统模型;采用AMESim/Simulink分别对带式输送机的机械液压部分和控制算法部分进行建模。仿真分析结果表明,在动态矩阵和PID串行控制下,带式输送机拉紧装置张力控制系统对延时和变结构有很强的鲁棒性,张力峰值小,能精确地跟踪张力设定值。In view of problems of nonlinearity,large inertia,hysteresis and time variation of tensioning system of belt conveyor,a mathematical model of tension device was established,and it was proposed to connect a correction links in series to eliminate system shocks;it was proposed to combine dynamic matrixcontrol with PID control to design tension control system for tension device of belt conveyor,making good use of advantages of strong anti-jamming ability of PID control and good adaptability to inertia and retardation of dynamic matrix.AMESim/Simulink was used to model mechanical hydraulic and control algorithm of belt conveyor.The simulation analysis results show that under serial control of dynamic matrix and PID,the tension control system of the tension device of belt conveyor is robust to time-delay and variable-structure,has low peak tension,and can precisely track tension settings.
