| 英文摘要 |
| With the rapid development of the installed power and mining capacity, the control effect and dynamic performance of the traction system have seriously influenced the working stability of the shearer. Although the traditional
master-slave control is widely applied in the dual-motor traction control of the shearer, it has caused the lagging of synchronization performance and can lead to unbalanced state of the traction system. Besides, for traction systems of the shearer
which parameters are subject to perturb and load is easily to disturb, PI (proportional-integral) control may not achieve
desired performance due to the structural limitation of PI controllers. To enhance the performance of traction system of
the shearer and achieve the power balance of the traction dual-motor, according to the structure of traction system, a novel
dual-motor control strategy based on active disturbance rejection control is proposed in this paper, which speed control
adopt master-slave mode and torque control use cross-coupling model. The proposed control strategy and the traditional PI
control are compared and verified by simulation and experiment. The results of simulation and experiment demonstrate that
the proposed control strategy has realized the power balance of the traction motors and improved the control performance
of the system. |
