摘要
针对恒速运行模式下长距离带式输送机运输系统长期处于“大马拉小车”状态以及多驱动电机控制结构复杂、速度同步性能差等问题,提出电机集群单元化控制和基于自抗扰控制的变速节能控制策略。在电机集群单元化控制结构下进行了并行、偏差耦合控制性能对比试验。建立长距离带式输送机功耗模型,根据提出的变速节能控制策略,基于PI和自抗扰控制搭建仿真模型并进行性能对比分析。结果表明,在变速节能控制策略中,自抗扰控制比PI控制精度高、抗干扰性好。
Aiming at the problems of long-distance belt conveyor transportation system in the state of“big horse-drawn trolley”for a long time in constant speed operation mode,complex control structure of multi-drive motors,and poor speed synchronization performance,the motor cluster unitized control and variable speed energy-saving control strategy based on active disturbance rejection control are proposed.The performance comparison test of parallel and deviation coupling control is carried out under the motor cluster unitized control structure.The power consumption model of the long-distance belt conveyor is established.According to the proposed variable speed energy-saving control strategy,the simulation model is built based on PI and active disturbance rejection control,and the performance is compared and analyzed.The results show that in the variable speed energy-saving control strategy,active disturbance rejection control has higher precision and better anti-interference than PI control.
