针对带式输送机永磁驱动系统采用PID控制器进行控制时电机的控制性能差和采用多电机驱动时电机间转速不同步、稳定性差等问题，提出了带式输送机多永磁电机驱动系统自抗扰同步控制策略。基于自抗扰控制(ADRC)技术设计了2种调速控制策略，并搭建仿真模型进行了对比试验；随后结合模糊PID控制技术对传统偏差耦合控制进行结构改进，并以矿用带式输送机多永磁电机驱动系统为控制对象，开展基于主从、传统偏差耦合和改进型偏差耦合同步控制结构的仿真。结果表明,基于二阶ADRC和改进型偏差耦合控制结构的带式输送机多永磁电机驱动系统同步控制策略具有更好的抗干扰能力、控制精度和同步性，有利于带式输送机平稳高效的安全运行。

Active Disturbance Rejection Synchronous Control Strategy of Permanent Magnet Motor Drive System for Belt Conveyor

The control performance of permanent magnet direct drive system of belt conveyor is poor when PID is used for speed regulation control, and the problems of asynchronous speed and poor stability between motors occur when multiple permanent magnet motors are used to drive at the same time. The active disturbance rejection synchronous control strategy of multi-permanent-magnet-motor drive system of belt conveyor is proposed. Based on the active disturbance rejection control (ADRC) technology, two speed control strategies are designed and the comparative experiments are carried out by building a simulation model. The optimal speed control strategy is selected, and the structure of the traditional deviation coupling control is improved by combining fuzzy PID control. Taking the multi-permanent-magnet-motor drive system as the control object, the synchronization control experiments based on the master-slave, the traditional deviation coupling and the improved deviation coupling synchronization control structures are carried out. The results show that the synchronous control strategy of multi-permanent-magnet-motor drive system for mining heavy belt conveyor based on second-order ADRC and improved deviation coupling control structure has better anti-interference ability, control accuracy and synchronization.
